Only one unlicensed game with a protection chip works correctly per Regen session. That is, if you play one such unlicensed game, close it, then some time later (possibly with some licensed games in the meantime) load another unlicensed game with a protection chip, the first unlicensed game will work correctly, but the second unlicensed game will show glitches resulting from the protection chip not working.
The games I have tested this with include Elf Wor (Unl), Smart Mouse (Unl) and Squirrel King (R) [!]. Autofix Checksum is enabled as is required by all these games.
Also:
Actually, does the default of 488 cycles/line correspond to no overclocking at all? Is 488 cycles/line correct for NTSC, PAL, or both? Sorry I don't really know a lot about the Genesis internals.AamirM wrote:Noted down. A dirty way to turn off overclocking is to restart the emu :) .
