Flash Advance

From PHWiki

The very first GBA flash card.

It was the same size as an original Game Boy cart, with a warning label that it'd fry if you put it into a GB/C.

The kit was made by Bung and based on their GB XChanger, using a linker connecting to the LPT port.

The chips used in the card were too slow, causing games to crash. Some games could be speed hacked to slow them down, preventing the crashing.

The improved Flash Advance Turbo came out just a couple of months later and fixed the speed issues.
