Various Errors with G.I. Joe: A Real American Hero from Cartridge - Jailbreak v6.5

EDIT: Made note of an additional issue and updated whether the issues are present on just the cartridge or the ROM also.

I noticed three specific errors when playing G.I. Joe: A Real American Hero from the cartridge on the 6.5 jailbreak firmware.

The first is some graphical errors during the brief cutscenes before each mission. These are incorrect 16x16 pixel sections of the background. Gameplay is unaffected.

The audio in the game is also played incorrectly at times as if it is slowed down. Occasionally, sound effects will get “stuck” and continue to loop only stopping when the effect would normally be heard again. There’s also occasional garbage heard on the Noise Channel.

Both of these issues are only present when the game is played from the cartridge. These errors do not occur with a ROM loaded via the jailbreak.

The third error occurs when a controller is plugged into the second port. The game quickly jumps to the character selection screen as if Start had been pressed several times on the opening screen.

During gameplay, pressing Start to switch characters causes the screen to briefly display before resuming gameplay, again as if Start had been pressed twice.

Removing the controller from the second port causes the game to function as intended.

This issue with “phantom” inputs when a controller is in port two is also present when using a ROM from the SD card.
