I have an original Super Mario Land 2 that came bundled with my GB Pocket over nearly 10 years ago. Super Mario Land 2 fails to work on my my GBA (Original Version) and my GBA SP. I can't test it on the GB Pocket because it's trashed. The game fails to boot up (showing a frizzy "GAMEBOY" Logo) sometimes if Im lucky I get to the title screen only for it to crash again during the save select. Similarily the same thing appears to be happening to Legend of Zelda DX, before the final boss in the egg the game crashes, something that never use to happen before. Ive cleaned the catridges and the gameboy's but it makes little difference.
