UN-FREAKING-BELIEVABLE!!!! While I've been working on fixing the last couple of bugs in the Mario Kart 64 DC port, getting us ready for the alpha release, jnmartin has gotten STAR FOX 64 up and running on the Sega Dreamcast in just two freaking days!?!? Sure, there are plenty of graphical glitches, and there's no audio yet... but W T F, it even runs well already!?! Freaking INSANE!! Anyway, surprise! The next N64-to-DC port has been chosen! Practice your barrel rolling, Dreamcast fans!

Sooo... How's our port of Sonic Mania to the Sega Dreamcast coming along!? SHE'S ALMOST DONE! We're getting ready for release!!! As you can see from these direct hardware captures, the game looks and runs amazingly on the DC! Multiple beta testers have now cleared the game on both Mania and Encore modes! Jnmartin worked his butt off finishing up the remaining effects, Michael Fadely is working on the final bit of polish, such as making sure the menu button icons show Dreamcast controller graphics, and I just opened a PR to put the gameplay code on the latest SH4ZAM commit... STAND BY FOR THE BLUE BLUR'S EPIC RETURN TO THE SEGA DREAMCAST!

Jesus Christ, jnmartin has officially implemented his first big improvement over the N64 original for the Sega Dreamcast port of Mario Kart 64! Now the jumpotron monitor screens in Wario Stadium and and Luigi Raceway are updating at a full 30FPS, or 6x the framerate of the N64! ...and he's doing this entirely in software with the DC's SH4 CPU performing slow, direct VRAM reads from the framebuffer into a temporary buffer in system RAM which is later passed to OpenGL which transfers it back into VRAM to update the jumpotron texture with... and the freaking Dreamcast doesn't drop a frame doing all this shit! Might want to keep that in mind, as a community... That accessing texture memory or the framebuffer directly from the SH4 via the "uint16_t vram_s[]" symbol that the video API within KallistiOS exposes, while comparatively slow, is not actually so slow as to be unrealistic for a well-optimized game to do anything useful with... very interesting!

With all of the excitement from Mario Kart 64 coming to the Sega Dreamcast, I've been getting bombarded with questions about whether any more progress has been made on our Mario 64 port... so here's a direct hardware capture of the latest build running on DC! The answer: HELL YES! Last time most people saw or played this port, it was plagued with performance, audio, and graphical issues... but as you can see from this footage, almost all of them have been resolved, and she's playing like a dream on the DC now! Wtf happened? Well, first of all, in the 5 years since the port initially started, I, along with others, such as UnknownShadow, have made progress optimizing and improving upon our OpenGL 1.2 driver, "GLdc," which drastically improved the overall performance of the port by decreasing the amount of time the Dreamcast's SH4 CPU spent on T&L, processing polygons. Next, chad developer, Bruce (or Bruck or Brucilicious, depending on who you are), went through and applied a bunch of bugfix patches from the upstream repo to the game to fix the majority of the graphical glitches such as clipping issues and Mario's iconic biker mustache from the previous releases (despite me trying to convince him to keep that one, as it's become a Dreamcast trademark). Finally, the original developer behind both the Sega Dreamcast and Sony PSP ports, MrNeo, has returned from hiatus and has begun redoing the audio engine to fix the artifacting and stuttering! Stay tuned for further updates and the inevitable rerelease of this N64 classic on Sega's finest little white box that still refuses to die!

JNMARTIN HAS BROUGHT US CHRISTMAS EARLY THIS YEAR!!! His port of Star Fox 64 to the Sega Dreamcast is officially complete and was just released! Here's 9+ minutes of spliced direct hardware captures, featuring footage from every mission running on an actual physical DC at 480p! I have to say, the game feels incredibly smooth and responsive on the DC and controls extremely well. Also... as you can see, at twice the resolution with progressive scan, she looks gorgeous even with my cheap-ass HDMI cables and USB capture card. While jnmartin had the game up and running on DC within (literally) 2 days, there was an enormous amount of time and energy invested into faithfully recreating the experience graphically, implementing various bugfixes, and hunting for performance gainz... the man has never been satisfied with anything short of amazing with his ports, and it really shows. Like his Mario Kart 64 port, Star Fox 64 is also using my SH4ZAM library to hardware accelerate the math and linear algebra routines for DC; however, unlike last time, he's gotten so good at performance gainz that I barely did anything at all on that side, other than writing a few little inline SH4 ASM routines to cover some operations that I didn't already accelerate within the API... Suffice to say, though, that everything from the vertex TnL pipeline, to audio decoding, to gameplay-related trigonometry routines has been optimized for the SH4's FPU... jnmartin even got to bust out the SH4's MMU to accelerate the translation of of the segmented address scheme used by the game on N64 (which was apparently some suggested memory management model in the N64 docs) into the DC's virtual address space--which previously had to be done in software... So even more gainz! Sorry, though... but pretty sure this is why the game won't work in the Flycast emulator currently... whoops! 🤣 Shout-out to darcagent for contributing DREAMCAST RUMBLE PACK SUPPORT (among other things) to the release. Rumble support has historically been a pain-point within our KallistiOS homebrew DC SDK, as many 3rd party rumble packs are non-compliant and either do what they want with certain rumble commands or screw up the entire maple bus when they receive something they have decided not to fully implement... Great job getting that shit sorted out and tested with so many packs. All of my exotic (and cheapo) 3rd party rumble devices that I was able to test with seemed to work great! Finally, lets give SonicDcer a round of applause for being the lead dude behind the original N64 decompilation--as it was his original work that allowed for any of this to even be possible. He also continued to offer support and advice throughout the entire porting process, like a total chad. Here's the link to the official GitHub repo with instructions for building a Dreamcast image from a StarFox N64 ROM:

The time has finally come! Here's an actual hardware capture of me cruising through Corneria in jnmartin's port of Star Fox 64 running on the Sega Dreamcast! As you can see, the port has been progressing PHENOMENALLY over the last couple months. Everything plays super smoothly and is as responsive as lightning! The visuals also look clean and crisp rendered at 480p with the DC's PowerVR GPU. We're estimating that the port is about 95% completed, with the majority of the last few weeks being spent implementing the lighting and other special effects for certain areas (which you will soon be seeing as well). Finally, he's been working daily on JIT compiling the N64 display list code into SH4 assembly in real-time in addition to using my SH4ZAM library for what he hopes will be a final round of additional performance gainz! TL;DR: We have another AAA-quality Nintendo 64-to-Sega Dreamcast jnmartin port on our hands here! Stay tuned for the upcoming release!

I think it's time we all get a reality check on Diddy Kong Racing 64 for the Sega Dreamcast, including myself... So here it is: original DKR for N64 vs our ported DKR for DC, direct comparison with FPS counters enabled. The truth is that I've been staring at the FPS meter all weekend, obsessing over every little dip, vectorizing, loop unrolling, and optimizing every little expensive-looking loop I can see in the codebase to win back 0.1FPS at a time... totally losing sight of what the basis for comparison even was from the original... So how long has it been since you've played the original on N64? I'm not talking about via emulation with higher FPS and fancy upscaling. I'm talking about directly, on an actual, physical Nintendo 64. Full disclosure... prolly been half a decade now, for me! Anyway, the devs behind the decomp were kind enough to share with me some of their performance and timing analysis captures... so I figured we'd take a step back and have a little fun! I had no idea it was running at only 20FPS tops, capped at 15FPS for the WizPig races!? I just remember pissing myself at having never seen a game look that good or realistic in my entire life back in 1997 when DKR came out for the N64... All I know is I want to do this game justice... but the truth is that even though we're still cooking, already the Dreamcast runs consistently at 10FPS higher and runs at 4x the screen resolution with progressive scan output... What do you guys think? How's our port comparing?🤔

Ocarina of Time, running natively on iOS and iPadOS for the first time. Not an emulator. Ship of Harkinian has run on Windows, Linux, macOS, Switch, Wii U, and Android. Never iOS. Now it runs on iPad, with iPhone in the build too. The game was decompiled to C and rebuilt as a native ARM64 app rendering through Metal. No N64 hardware being simulated, no ROM interpreted at runtime, no streaming from a Mac. It isn't stuck at the N64's 240p and 20fps. Widescreen, full resolution, 60fps. This game deserves a controller, so controller support is native. Pair a Bluetooth controller and play the whole thing. Touch, keyboard, and mouse work too. I used Codex 5.6 Sol to build the iOS layer. Open sourcing it all below.

Mario Kart 64, running natively on iOS and iPad, with touch controls designed for racing. The Mario Kart 64 decompilation community spent years reconstructing the original game code in C. Harbour Masters turned that into SpaghettiKart, the source port. I built the iOS layer on top. Not an emulator. The game code is compiled for ARM64 and renders through Metal. Your ROM is only used to generate the asset archive, on device. No N64 hardware being simulated, no streaming from a Mac. It isn't limited to the N64's original output resolution, and MK64 Reloaded's HD pack replaces the original artwork on top of that. That's the pack running in the video. Steering is genuinely analog, not left and right taps. Separate layouts for iPad and iPhone, and optional tilt steering. Pair a Bluetooth controller and it takes over. Four-player selection works and two-player split screen runs. Two other public SpaghettiKart iOS builds exist, Sunset-Dawn's and rebelancap's. Both install on an iPad. Neither was built around one. SpaghettiPad is. I built the iOS integration with Codex 5.6 Sol. Repo, guide, and IPA below.

IT'S FINALLY HERE! #Doom64 has officially landed on the Sega #Dreamcast with this flawless, AAA-quality port by jnmartin. I've been following his work the entire time, beta testing (and making sure we didn't break anything in KOS), and it has been an absolute pleasure to see how much care and attention to detail has been put into bringing this #N64 classic to the DC! He has released all of the source code and tools required to build and play the game on his GitHub... but there are still a few small additions I would love to see the community pitch in to help with. It already has some bitchin' VMU icons, but we should definitely add support for: Mouse + Keyboard, Dual-analog sticks, and Rumble packs, to ensure that the DC port is the definitive version! #gamedev #retrogaming #doom

While reading the responses to jnmartin's #Doom 64 port to the Sega #Dreamcast, I stumbled upon the comments of a few haters who were stating that the DC version had absolutely NOTHING to offer over the Steam and Switch versions, claiming that we're just a community of wishful thinkers living in the past... OH. REALLY, NOW!? Actual hardware capture on the left of me playing the Steam-exclusive map, "Wretched Vats," on my DC, while the right is a recording of the same area from the Steam version... The Dreamcast version only offers up to 16 simultaneous dynamic lights onscreen, bump mapping on environments and weapons, controller (with dual analog) + mouse + keyboard support, VMU icons showing damage, quicker startup times, no forced online registration, supports all of the new Steam-exclusive levels, and now, for the first time ever, also runs mostly at 60fps... I do believe you've been Dreamcasted, haters. PS: When the algorithm inevitably destroys the footage due to compression, here's where you can download the original: #gamedev #retrogaming

Today, PH3NOM brings us the historic gaming blasphemy to end all blasphemies... A little tech demo of a scene from Resident Evil 4 recreated within the PH3NOM engine... RUNNING ON THE SEGA DREAMCAST!!!! Here is a direct hardware capture of me playing on a stock DC, recorded with just a cheap-ass HDMI cable being fed into a cheap-ass USB capture card... admittedly after maybe 15 minutes of practicing to not embarrass myself. 🤣 I am so beyond impressed, though, at what I'm seeing from PH3NOM, after simply a week's worth of hacking RE4 models, assets, and behaviors into a totally different engine, which was written from the ground up to target the DC's unique hardware. If one (albeit extremely talented and accomplished) dude did this as a tech demo with a general-purpose DC engine in a week... Imagine what a well-funded team from Capcom could've done with support from Sega, had the Dreamcast stuck around and received an official port...

The Legend of Zelda: Majora’s Mask, running natively on iOS and iPadOS. After Ocarina, everyone asked me to bring Majora’s Mask over next. So here it is. Not an emulator. MaskPad is built on Harbour Masters’ 2 Ship 2 Harkinian, itself built from the community Majora’s Mask decompilation. My work was adapting that existing source port into a native ARM64 iOS/iPadOS app rendering through Metal. No N64 hardware being simulated, no ROM interpreted at runtime, no streaming from a Mac. 2S2H isn’t stuck at the N64’s 240p and 20fps. Widescreen, full resolution, 60fps rendering. This game deserves a controller, so native game-controller support is built in. Touch, keyboard, and mouse work too. I used Codex 5.6 Sol to build MaskPad’s iOS layer. Source and guide below.

Been optimizing my ASS OFF now that jnmartin has pushed all of his progress on his Star Fox 64 Sega Dreamcast port to a private GitHub repo to collaborate with a bunch of us DC devs before release. MAN this thing is HIGHLY optimized already... We're essentially running a high-level emulator for the N64's RSP coprocessor, doing graphics transforms, matrix math, and display list conversions not only on the main SH4 CPU, but also sitting atop a high-level OpenGL driver, in real-time. Not only that, but once again, we're doing all audio synthesis and mixing also on the main SH4 CPU, so this thing is doing a literal asston on the main CPU with what might seem like a relatively straightforward port. 99% of the time, everything runs flawlessly, but when you drop a bomb on a shitfest of enemies in a densely populated area, as with the N64 original, the FPS can dip momentarily. Here's a direct hardware capture of me testing a new SH4 optimized routine out for gainz on my Sega Dreamcast... this mofo is meant be used for one-off 3D vector transforms by a single matrix which has not been preloaded into the XMTRX FP register matrix back-bank. Rather than doing a full 4x4 load on the matrix just to do a single 4D transform via the FTRV instruction, we're simply peforming 3 3D dot products against a single 3D vector, allowing us to pipeline the loads, dot products, and store operations better than doing a load all at once followed by a transform, and we aren't wasting a lane on the FPU for a 0.0f W component!

I wanted to show you guys how hard we've been working to get the Diddy Kong Racing decompilation to run this well on the Sega Dreamcast... So I took the liberty of splicing together some high-action moneyshots directly captured from the console for a look at how the game currently performs. Just a few days ago, it was dipping to below 20FPS with audio cutting in and out as the main thread couldn't keep up with the audio decoding while simultaneously handling rendering and game logic. I know, I know, how could a Dreamcast struggle with an N64 game? It's because these decompilations are written to essentially emulate the N64's unique hardware as accurately as possible. In this case, that means the Dreamcast's main SH4 CPU is emulating all audio decoding, mixing, and synthesis in software, including DSP effects. This was originally handled separately by the RSP coprocessor in the N64... Not wanting to have to rewrite the entire audio back-end to use the DC's AICA sound processor, I've vectorized the absolute living HELL out of the ADPCM decoder with my SH4ZAM library... Which gave us enough performance out of the SH4 to continue emulating all of the sound processing in software. You will notice in the footage that the only time the FPS isn't at solid 30 is when there is a lot of overlapping SFX from nearby racers chattering or items getting used. That's the SH4 having to work even harder to mix multiple audio channels together and possibly even apply DSP effects to them as well!

WHOO!!!! This is an actual hardware capture of Michael Fadely's INCREDIBLE port of #SonicMania to the Sega #Dreamcast, compiled with the latest SH-ELF-GCC14.1.0 toolchain, running on the tip of the KallistiOS SDK's master branch, streaming in assets from the virtual filesystem over the network, capturing stdout/stderr from the DC! Running like a boss! We got Michael Fadely showing us around the app-level code he beautifully ported, me on SDK/OS duty, making sure we didn't break anything with all of the new features and commits, and Oleg Endo on compiler duty, since we found an ICE with GCC14 getting pissed off over some stateful C++ lambda in the render path... Eggman is so screwed. DREAMCAST COMMUNITY, ASSEMBLE!!! #retrogaming #gamedev #cpp
