Sega Genesis Blast Processing MAXED OUT ??? Whats better than 660 sprites in 660 colors (prev demo) ??? 1013 sprites in 1013 colors !!! Demo starts at 117 sprites then adds 20 sprites per second every second until it reaches Max Blast Processing at ~ 46 seconds mark. Live...

This demo is something to stand up and applaud loudly, I think no one imagined how far MD can go and it is one of the reasons why it is my favorite platform, every day something comes along to surprise me in any aspect, be it graphics or audio.

@AlexisynthPanto Thanks Alexis for the kind words. Blast Processing may not be a specific term but the community knows exactly what it means, and we're not even close to done 35 years later !!

The Sega Genesis was ahead of its time despite its limitations I knew I chose the right 16-Bit console to own & love ❤️ Still being sold in Brzail today is a testament to its significance

@PS4Revolution Thats amazing that it still being sold in Brazil, testament to the longevity of the system. Limitations are what attracts me to retro systems, make you work hard and flex your mind to be very creative. Unlimited power is of no interest to me - retro ftw.

Warning : Blast processing overdrive !! Whats better than 440 sprites in 440 colors on Sega Genesis (eg last sprite multiplex demo) ? 660 sprites in 660 colors !! Did away with interupts and now fully racing the beam, Atari 2600 mode basically ! 3 sprites re-positioned and colored every raster line (a full sprite palette every 5 scanlines). Ran out of Total Palette 3/4 down screen, 512 colors total on Sega Genesis so enabled shadow and highlight mode to get extra colors from there on. Runs 60 FPS and have the full Vblank left too and dual backgrounds to play with yet !! GENESIS DOES !! #SGDK #SEGAGENESIS

** SEGA GENESIS / MEGADRIVE Software Scaling + Rotation *** Sega Megadrive can't scale backgrounds and rotate sprites in software at the same time ?? - hold my beer !! After Scaling I've been tinkering with Rotating sprites in software and I think it looks pretty sweet ! In the video 4 * 32x32 sprites are rotated through 64 steps at 30 FPS in software, it could be 60 FPS and more rotating objects if we were not doing the scaling at the same time but even blast processing has its limits ;-) Rotation at 30 FPS is far smoother than you typcially see in even in pre-rendered rotations anyhow ( a 64 frame 32x32 rotation is 32kb - not small ). Challenges were make it fast : very fast as this needs to work at pixel level, not double pixel like scaling. The megadrives packed pixel format (2 pixels per byte) makes that a little bit tricky . When I started the algorithm was 3x slower than now. Make it sensible : has to be usable in game , had to present a rom size reduction over pre-rendered animation. Make it flexible : so we can rotate frames in the background using up idle cycles (end of frame) and store those frames to vram for very heavy cpu scenes, so we can still have very smooth rotation with very heavy cpu demands still. Thanks to my team Carsten666 for the GFX and CYBERDEOUS - Crouzet Laurent for the marvelous tune. #SegaGenesis #SegaMegadrive #SGDK

Would this be one of the worst seasons of Fortnite ever if it wasn't for the sprites? I feel like the sprites are carrying BIG TIME this season. Every shotgun feels like crap and the movement is not good at all. BUT collecting sprites is sooooo fun!!! What do you think? How would you rate this season without taking the sprites into consideration?

Made a Family Portrait explorer for send/receive. It loads your token, and then slowly accumulates sprites filling the screen until there's no more room. Zoom in and out and pan around to see everyone's sprites as they appear. 👇

*** SOTA RETROCON S.O.T.A UPDATE *** Whilst the Versao LTDA team is busy at Retrocon showing off our latest Sega Genesis SOTA update, here is a small snippet of how the game is progressing. This video has 3 parts, our menu screen, rain - wind sub section of level 1, then the boss. Everything is still wip including my gameplay skill lol ( and i thought the controller would help .. ) Some challenges overcome : The Menu screen uses shadow and highlight transparency modes in two ways, the background mode for the light rays and then the sprite mode for the mist - it has a nice overlapping effect too, due to using the forground plane for the light rays (s & h background mode) the entire forground is made up of sprites - all the words are sprites . SaviorMarks sent me a screenshot of an issue with boss leftover Mist sprites affecting the menu screen and I thought that looks really cool - lets do that haha . Sometimes bugs are keepers !! The rain section uses more than 80 sprites, a sprite multiplexor handles the rain whilst normal non plexed sprites make up the moon / clouds in the far background , the lamp posts and lamp light in the mid forground and Fences in the front forground . Without the multiplexor there was too much drop out on the rain at times. The rain is still blinked in alternating X positions due to the pixels per line limit , but it gives a great result still. The lamp lights use Shaded Active Dither as S&H here would not overlap the enemies / player . The Boss was a challenge with its size and full frame updates, up to 650 tiles are changed per animation frame into vram. Custom Dual priority DMA routines and extended DMA timings are used (still NTSC 224 pixels tall screen size but most of the vblank was used for updating tiles ) . These methods were used to update the bosses dual display buffers. I needed to have dual priority DMA buffers as the player / waterfall etc had to update their frames whilst the boss is constantly streaming tiles. There are also S&H transparent Mist sprites used for the boss sequence. It seems if you want everything to break at once target a demo for a retrocon event haha, we had lots of issues mainly with vram getting stomped and as all animating sprites need to be DMA streamed to fit into VRAM as the forgrounds and backgrounds take up a lot of tiles. Some new tools which show the VRAM allocation for the sprite engine on a frame by frame basis helped and a self defragging VRAM system helped quite a bit also. Thankfully things are in a good state now apart from a couple of small bugs that persist. Thanks to SaviorMarks and GamesCare for putting up with and testing all the bugged updates haha !! #SegaGenesis #SGDK GamesCare SaviorMarks #VersaoLTDA

This is so, so, very tedious to add. But it is working, combined sprites for the variations. Now to just apply it to every single race one sprite at a time.

"Vampire Queen" is an Adventure Time one shot with a really cute art style by Myxtii. I love the colors on the backgrounds and sprites, really makes the art pop out more! Followed with the nice music by Box :3📦 🇵🇸 (COMMS OPEN!!) , this is a great mod to get comfortable and vibe to. Play it!!

** SEGA GENESIS - LUFTHOHEIT - Tunnel Stage Preview ** We are pleased to show an early preview of part of our Tunnel/ Vortex Stage. Big shout out to Carsten666 for his gorgeous Graphics, CYBERDEOUS - Crouzet Laurent for the amazingly well matched Audio to this level, Stephane for creating SGDK in the first place and being very supportive with new features in SGDK also. Technically this stage was a bit of a challenge, some notes below re this. To drive the rolling texture of the background - 40 horizontal interrupts are used, executing 120 scanlines of color change, changing 5 colors per line = 600 color changes per frame. Variable spaced interrupts are used for expansion / compression effect. Four stages of brightness used for every texture / pattern , darkest in the center of screen , brightest top & bottom. New colors created by alternating two similar colors at 60 hz, for seams between brightness regions to increase the blending between regions. Co-operative Multi-threading system used to reclaim huge amounts of CPU within the color change interrupts. For example all rolling Cannon & Cannon bullets and Debris are moved using this technique - up to 25% of total CPU can be reclaimed ( its normally wasted polling for rhs/hblank ). Heatseeking missiles, these need trajectory's recalculated frequently and doing that at speed can be tricky - lots of missiles launched at Mid video and its the heaviest CPU load in the demo ( these are not using the Multi-threading technique yet ). Variable rate collision checking, as bullets gets very close to player the checking is done at 60 fps, as they get further away the checking drops off rapidly - this saves cpu. Runs 60 FPS at all times, works on real HW also but captured on emulator as my phone doesnt take 60hz video without getting out of sync. Intro & Foreground effects are coming, currently no foreground is present as its not quite baked enough yet, we have some cool things we will do with the extra plane yet. Lots of good stuff to come !! #SGDK #SegaGenesis #SegaMegadrive

*** Mega Parodius Sega Megadrive Update *** Lately I've been having some fun seeing how far we can push the Parodius game engine . This is not arcade accurate - just for testing, decreased bullet timers and upped the bullet count to see what would happen re cpu usage when things are made a lot busier ! Maybe something like this could be insane mode in the options etc. Since last update we are a lot more optimised under the hood . The C based sprite engine, particularly visibility checking was speedup , overall 25 % faster. Then re-wrote the sprite engine completely in 68k assembly , 30% faster again. It took about 3 days and 1500 lines of assembly , thankfully the gains were worth it. All these gains will be back ported to S.O.T.A also as its using the same sprite engine. Usage is around 19% of cpu per frame with a full sprite load - 33 % cpu left in the busiest frame currently . Parodius is using a write the sprite list every frame type engine , so priority and meta-sprite objects can be handled with ease albiet its still a bit slower than static allocation sprite engines such as the one in lufthoheit but this is a bit easier to code for in the long run. All collision checks are been done , we are using a spatial grid system to get the collision checks done faster than a brute force approach . To get to maximum sprite count destruction is disabled in the video. We hit 80 sprites onscreen in this sequence , the sprite counter is one the Left side. We use about 16 sprites in the top hud and water line , about 21 for player attacks / missiles / shots / options . Up to 35 bullets + enemies . No lazer usage here as the Lazers use zero sprites thanks to the raster tricks , this video is all about the sprites ! Improved the water line when the Catboss is active , as he is Sprites + Forground we are doing some tile rotation tricks eg bit scrolling to give the impression of parrallax at that point . Vector Orbitex has updated the stage 1 music again and has made things even higher quality , hes mixed pcm and fm channels together to create higher quality orchestral hits for example . Pyron has started converting assets from stage 2/3 , some amazing work there . Hes well ahead of me at present which is a good thing. Still lots of incomplete animations missing logic etc , its slow going with RL getting in the way haha and 2 other projects !! Still its fun !! #SGDK #SegaMegadrive #SegaGenesis #Parodius
