Put the processor in a halt state and then override the address lines to read through memory sequentially. But I don't know how to override the data lines.ģ. And one would need a microcontroller with 4mb of RAM (or use a PI, but one would need some gpio extenders, and that might not be fast enough).Ģ.Find some way to inject code to the 68000, say by overriding the data lines, and then force the 68000 into a loop that just reads all of memory, and record the data as it comes in over the data lines. emulators, Mega Everdrive, project MiSTer, etc.).

I am wondering if there is some way to exploit these to dump the data from an emulated game cartridge while the game is running (e.g., using a microcontroller or a Raspberry PI).

GamesSonic Riders (GameCube) Main Get Started Sections Mods351 Requests4. And the processor is under an epoxy blob. The ROMs are presumably on the MSP55LV512 flash chip, but the chip is BGA so there is no easy to hook up leads to it to read data from it without desoldering it. This is one of the super-cheap old units that have a composite TV out. In conclusion, if you find this one (which I believe it's a bit rare) get it, even if you played those games before.I've been trying to think how to extract ROMs from an AtGames Genesis classic, largely for kicks rather than for any practical purpose (I already have most of the ROMs from the Steam and Amazon Appstore Android Sega collections).
