Export custom graphics changes to new rom #88

Closed gingemonster closed 5 years ago

Maybe I am missing something but is there a function that allows me to export a rom once I have added custom graphics?

Custom Graphics aren't injected or added to a ROM. The ROM itself is left unchanged. All GBE+ does is look at the dynamic data stored in VRAM at any given moment, then instead of drawing normal 8-bit Game Boy graphics, it draws user-generated graphics. It's basically the equivalent of "HD textures" popular for N64 emulators or in Dolphin. Nothing about the game itself is changed, so there's no way to send those changes back to the ROM.

that's a shame, thanks for explaining
