Problems dumping Sega Megadrive games? (SOLVED: FORCESIZE=#)

[Armageddon Potato]

Hey guys! I just dumped a few Sega Genesis & Megadrive prototypes for myself that I own using a Retrode, however one of them will not work in any emulator properly. The title screen shows the logo, then the screen flashes white and plays the music, and I can't play it. The game is Gunstar Heroes (but the dumped file is called "Lunatic Gunstar".)

The game works fine in my Sega Genesis, why isn't the dumped file working correctly?

Edit: SOLVED! I had to set "forcesize" to 32 in the Retrode configuration. Gunstar Heroes is a 2mb game, and the original dump I had was only coming out at 512k!

Seeing as it's a beta, it may have something not supported by the emulator in it. Do you have a flash cart you can put it on and test it on a real Genesis?

I don't have a flashcart for sega genesis yet. Someone suggested doing an overdump. How would I do that?

Please send a copy of your dump to support at retrode dot org, and I'll have a look at it...
