Ok so the saves are located in Saver, the current ROMs I have are(all U),Here are the ones that work with no problems Emerald, Firered, Final fantasy iv, Final fantasy i+ii dawn of souls, and zelda minish cap.
Here are the ones with new bugs not normaly in things like vba.
Pokemon Light PLatinum,--This one when loaded in psram makes the camera move super far away from the player and doesnt quite show the sprite in the correct spot, ie off the screen or a few blocks off the middle. Base Ruby(U)---I think, could be ruby(S), but idk.
Pokemon Victory Fire--- This doesnt allow saving, only boots in nor cause of 32mb size.
Pokemon Resolute----Same issue as Victory fire. Both have a base of Emerald (U)
My own Pokemon Valen---Freezees at title screen, I think its cause it uses a 256 color title screen, but Idk for sure. Base Fire Red(U)
Here are the ones that just straight up dont work
Pokemon Ash Grey--Base Fire Red(U)
My own Pokemon Blackened Night--- Wont boot at all, boots in other emulators so its not a game breaker bug.
And for the record, I did try and go through the begining coding of light platinum to see if there was a missing command to refollow the player with the camer, there was but adding it in doesnt change the issue.
I use Rudolphs gba backup tool to dump my files, andmy sd card is micro sdhc 16gb, but I tried a 8gb micro sd and there was no difference. Oh and my roms are stored in the base folder of the sd card.
