cv1k patcher

This page should patch any cv1k game with a set of selectable features.

All the patching happens locally, your file is not uploaded to my server. You can save this page to your PC and it will keep working offline! It only works on modern browsers (it was tested on Chrome 89 and Firefox 87).

Here you can select the features that will be patched:
Avoid checking U2 validity (useful for repairing PCBs with replacement flash).
Removal of background music.

Ready to patch - please click the button above and choose your romset zip file.

Modified roms can be played as follows:

• In MAMEUI, simply replace your romzet zip file with the patched one and start the game normally. MAMEUI will complain about the ROM being modified, but you can ignore the warning and continue playing the hacked game.
• In plain MAME, start a command prompt in the mame directory and type in the command "mame ibara" (replace ibara with whatever romset you are trying to play).
