I thought I'd have a go at this AI porting gold rush, so here is my attempt at Rolling Thunder for the NeoGeo. Enjoy. hoffman.home.blog/2026/10/28…
Rolling Thunder (NeoGeo AI Port)

Rolling Thunder (NeoGeo AI Port)

I’ve been porting arcade games to the NeoGeo for a while now. Shinobi, Golden Axe and a few others have all gone through the same grind: dump, disassemble, understand, rewrite, repeat. This t…

This is what’s going on in the lab now. Several computers connected to dedicated setups to validate existing work vs hardware and official data sheets at a level of detail we could not afford before. #MiSTerFPGA

OK, last tech post about Zero Wing. This is the custom layer tool I built. This allowed me to group priority tile sets from the games three background layers, which then get composited into one of the six parallax layers on the NeoGeo.

Again, preamble, if you don't like this feel free to ignore it. Marble Madness II #MiSTerFPGA core released! Yes, this is vibe coded, however, it uses real fpga schematics for known chips and is a full fpga implementation. Enjoy it! Or, well, don't. github.com/kandowontu/Marble…

Replying to @_ShootTheCore
The actual implementation requires much more information. I need to precisely measure everything from detailed information such as blitter's tRCD cycle, latency between the blitter FIFO and SDRAM, etc. Additionally, I need to verify the blending formula through pixel capture.

Operation Wolf has an audio filter only on one of the PCM channels. This is a feature present in real hardware which has not been emulated before. Coming up tomorrow on a new #MiSTerFPGA core

The uPD78C11 core is back! I originally made this core for Rainbow Islands, and it emulates the C-Chip. I had set it to private due to some bugs, but Claude put together a test bench in just 30 minutes to fix them, so I can now make it public again. github.com/ika-musume/IKA87A…

I think I've done something unique here: an entirely AI generated cycle-accurate CPU FPGA implementation. By given the agent access to a hardware harness that allowed it to run test code on the CPU and analyze it's responses it was able to recreate it in verilog.

Fixed a nasty glitch in Parodius (see missing line in CREDIT) that was due to a previously unknown operation of the Konami CPU. I had taken note of the unknown CPU operation and jwestfall69 (MAME) proposed the solution. Thank you!
