I should have asked first: Are you planning to make money with it? In that case, we should talk :-)

yeah, explanation was rough. white = currently being read or written the green/read areas tell whether the last access was a read or write.😅 (although writes/red takes precedence if both a read and write happened, cause I had to watch for RAM regions mistakenly overwritten)

Visualizing RAM access to debug saving. A peek into the NES's brain. #NESdev 1 pixel = 1 byte red = writes, green = reads, white = currently being accessed

Aaand the bundle is live with 4 days remaining. 30 quality NES homebrew games for $30! Micro Mages included! #N8ABundle
🚀 The New 8-Bit All-Stars Bundle is now live! Honestly, I still can’t believe we managed to bring together so many incredible NES & Famicom homebrew developers and games in one bundle. I hope you’ll enjoy it as much as we enjoyed putting it together. 🎮 itch.io/b/3695/new-8-bit-all… And if you’d like to help support the developers, please consider sharing the bundle with your friends, followers, or fellow retro gaming fans. It really helps 🙏❤️☕️ #N8ABundle #NES #FAMICOM #homebrew #nesdev #indieNES #NESmaker #indiegames #gamedev #ファミコン #同人ゲーム

Idk how much testing there was on real hardware, but given it uses the engine of the original Micro Mages, I'd be surprised if they didn't run

None, I'm afraid. The PS4 version has been developed by a third party and won't work on PC. :(

Added some compression into the mix et voila! Banks $03 and $05 look way less cramped now, that SHOULD be enough space to carry us through the rest of development :) #NESdev

We haven't posted in a while. Triple Jump is very technical and less visual currently. But here's how the 512KB MMC1 Triple Jump ROM allocates its space. The circled areas are small islands of unused space that we're hoping to tap into. They add up to a whopping 2KB! #NESdev
