So I picked up an EMS cart, and it came loaded with LSDJ, but it was an earlier version (4.6.3? I believe?) so I threw the latest build on there. I hadn't tried it before over writing the cart, but now it loads the Nintendo screen, and then goes to a blank screen. Adjusting the contrast doesn't even do anything.
I'm running 4.6.7 on both pages, with the .sav from when I was using BGB. The gameboy is a DMG-01 (basic one, not playitloud) and it's hooked up to the Rechargable Battery Pack. The gameboy runs other Carts fine (Tetris, Kirby Pinball, Yoshi's Cookie) but I have yet to try any other ROMs. I'm gonna try to load LSDj without a .sav and with an older build, but if anyone has any other ideas, they'd be greatly appreciated. I've already pulled the cart out/put it back in about a hundred times, tried waiting ten seconds, and turning it off and on.
Thanks everyone!
