Reminder that GRADIUS has a nice #CommodoreAmiga port named TINYUS (by Abyss, 2021). Runs on Amiga 500 1MB on a single floppy disk and seems to use reverse engineering of the original code for accuracy. More info: #AmigaReposts #gamedev #STG #グラディウス

We looked at the original code for general reference tho most of the things were recreated by just looking at the game running. This was much faster then going through all the asm. Most of the frametime goes into blitting stuff. Almost all code was done in C. Nice challenge.

It's awesome, great job! I've posted about it because I think it's underrated, in the sense that I rarely see it being discussed around here. It deserves more love. I had the MSX as first computer, then the Amiga. So, I imagined how "Nemesis" (as we called) would look on Amiga.🙂

@dantemendes, this sounds like a fantastic throwback to classic gaming. 🎮

Also it slowdowns a lot on a vanilla machine. But I mean, it's not as bad as Gradius III on an SNES, so it's really acceptable. The game itself warns us about it, that a 020 is better for full framerate with no slowdowns

Yes, it's discussed on the EAB link there. It's reverse-engineering of code written to run on a 10MHz 68000 + Z80 co-processor, against a single ~7MHz 68000 on Amiga. But I'm almost sure that the arcade had some slowdown too (most games had, even on faster CPUs, even Neo Geo).🙂

We needed that back in the 90s… I love the Amiga, but comparing Konami’s playability with Psygnosis or Team17 would be a bloodbath!

Game playability designed by a single guy that does everything (Amiga) versus Konami with multiple professionals in their areas. Just a matter of money and resources in the end, not "oh the talent blabla", that's bullshit from people who don't have any idea on game production. 🙂

Am I think only one who thinks this looks awesome, as good as the arcade!!

Sounds pretty great.

I found a pity the game doesn't loop like the Arcade one, and I found it to be easier than the Arcade. But it is an excellent port. Released back in the day, it would be a great game to have, even as a later game (Not like the Amiga had many shmups better than 1987 Gradius :D )
