Contra 3 does not work on real SA1 cart

Open badass-boss opened this issue 5 years ago • 4 comments

I tried Gradius 3 and Contra 3 on real SA1 cart with 128KB SRAM. I recorded both ROMs directly on cart. Gradius 3 worked for me, however Contra 3 refused to boot up at all for some reason. All I get is black screen. The cart configuration is exactly the same for both titles. Please help. Thanks in advance

Hi badass-boss, thank you for the issue!

That's indeed a known bug on my side and I'm working on a fix but I don't have an ETA yet. But stay tuned in here that I'll eventually post updates regarding the Contra III issue.

Thanks for your response. Fix for this would be greatly appreciated and I can cooperate and test updates on real SA1 cart

I do some tests and I got the following conclusions. On a real cartridge not works, but on the FXPAK works correctly ¿What diferencies have the SA1 implementation of the FXPAK between the real SA1 hardware?

If help is needed for testing, I also have prepared some SA-1 donors which could run this.
