New Contra III SA-1 Update - Now working on hardware
Added 2022-09-10 17:05:12 +0000 UTCHi. More good news! After fixing Gradius III and Super R-Type, which you can download the pre-release here, Contra III - The Alien Wars - with SA-1 chip support has been updated to work with real hardware too.
I remember that unlike Gradius and Super R-Type, which some people successfully managed to run on a SA-1 cartridge, nobody (as far I know) got Contra III SA-1 to run on SA-1 cartridge. I thought there was a mistake during the Contra III initialization code that I missed during the conversion and I never really got a clue on what was happening. But in the end, all of my SA-1 ROM hacks had the same issue: my boot time attempted using CPU stack operations before enabling I-RAM write. Somehow, Contra III was the most impacted, but the same issue - and root cause - was also present on all my SA-1 ROM hacks, including Super Mario World SA-1 Pack released over 10 years ago.
The new version of Contra III SA-1 now works correctly on hardware and you can download under the attachments section of this post. Don't forget that since it's a BPS patch, you need the original Contra III (USA) ROM and a BPS patcher to apply it. You can read more about it here: https://sneslab.net/wiki/How_to_apply_ROM_patches
Hope you like this early access patch and thank you, once again, for your long support; Comments and feedback are always open for me.
