I am looking into cheap handhelds that have a micro sd slot. I am testing one that you can find on Amazon by searching CredevZone x350. As far as I know, no one updates firmware for this one.
It plays Gameboy decently but there is a pretty significant problem: It refuses to open the 32kb Gameboy games. (Gameboy games were either 32kb, 64kb, 128kb, 256kb, or 512kb, with a handful that were 1024kb.) Only on the 32kb games does it say "Invalid File Format".
It seems like this should be a glitch that might be circumvented simply by editing the file instead of the problem actually being fixed.
I have tried appending 32768 bytes to the end of the game using a hex editor. Both with 00s and FFs. I have tried appending a duplicate of the entire 32kb bank to the end of the file. I still have the same glitch. I have also tried formatting the micro sd in various ways.
Perhaps it will require editing the header which I am only barely familiar with.
I have done some research on why this glitch might be occurring. (Some related information is in this nesdev thread.)
Oddly enough this thing comes with a "loaded" 8gb card, and of the 100 GBC/GB games, 4 of them are 32kb games. (Tetris, Dr. Mario, and a couple others.) Which don't work.
