I'm really struggling to get Mega CD to run on my Mister. Please help if possible.
Update all placed a "boot.rom" bios in games/MegaCD folder, as well as three others in games/MegaCD/Europe, games/MegaCD/Japan and games/MegaCD/USA respectively.
My USA folder is filled with folders of USA roms, each folder containing that game's .chd file. I switched to chd after bin/cue weren't working, and even switched back on some games for testing.
When I launch the core, It defaults to the US region, presenting a wallpaper of outer space. If I manually select other regions, the wallpaper changes, e.g. "Sonic with Mega Drive 2 logo" for Japan. I've even tried a region specific rom for Europe and Japan in those folders to no avail.
I feel like I've done everything right. Is there a step I'm missing? Does each game need its own BIOS file in the folder? I tried pressing "start" on these wallpaper screens, even after assigning my buttons.
Any help here would be greatly appreciated.
