Description

Happy Miku Day! To celebrate said day, I've made a Rom Hack of Mappy featuring Hatsune Miku! Not much of it changed aside from Mappy being swapped with Miku, and one of the items now being a leek, but a lot more will change in the future so stay tuned for that when you can.

3-3-2026: i changed it to a bps file, hopefully that actually works. who knows, it's been forever since i last did anything here

[QUOTE="Doom Guy584725, post: 4523, member: 1136"] Hi, I'm also the same as Retro Master HD, the Miku hack from Mappy doesn't work, and some emulators don't even read the modified ROM. Could you tell me why this happens or could it be something else? Greetings Retro. [/QUOTE] Greetings dude.

Hello, for some reason the Rom doesn't seem to work no matter how many times or whatever way I patch it it doesn't seem to want to play ball with my emulator it just keeps on coming up with unknown file format and I patched it to the correct Mappy Rom but still no luck, I used Flips which is the same program you used to create the patch which I tried patching the Rom Hack with and it would say that this patch is not intended for the Rom. Kind regards.
