Are you referring to ”PC Engine", "PC Engine CD". "PC Engine SuperGrafx"? This is the JP version.
Or the JP versions of "Sega Mega Drive", "Sega Mega CD", "Sega Super 32X"? In the case of Sega, the only difference is the color of the logo and buttons.
I would also be happy if they would also have a "Sega Mark III" version instead of the SMS version.(JP version)
If the PS1/PS2/PSP/PSP is the JP version, the decision cancellation of ◯ and × is reversed. Is there any chance I can solve this with image editing?
By the way, do you have any ideas for MSX/MSX2?
