I’ve created a set patches for a bunch of CV1000 games to assist with practicing on real hardware. Create your practice roms here!

Title Screens

Features

  • Stage Select on title screen. When freeplay is enabled or after a credit is inserted use left/right joystick on the title screen to select a stage before pressing start. After selecting your ship you will begin your credit at the selected stage.
  • Quick Restart. During a credit press A+B+C+Start (on either play side) to instantly exit back to the title screen.
  • (EXPERMENTAL) Fast boot. Skips the code area and free area memory checks, and performs a faster eeprom read for stored settings on boot. On real hardware this does not improve boot time by much, but on emulators this can save 20 to 30 seconds of boot time.

Notes

Please be aware these patches have not had enough testing done on them to be considered stable so please treat them as experimental. You may encounter graphic glitches or freezes. If any issues are encountered please provide the specific details so that I can try to reproduce and fix the problem.

Each stage starts the player with the power level that is assumed to be picked up by this point, assuming perfect play. Please let me know if any of these need to be adjusted. Counters and Gauages are variable by player skill so these are left at the default value.

Akai Katana includes a boss select feature which I plan on doing the same for every game. However, this type of feature makes creating the patches substantially more difficult and may not be possible with every game.

Deathsmiles and Deathsmiles Mega Black Label currently do not have stage select patches, more research is needed to be done to work out how to approach creating patches for these games.

Feedback is welcome, if you encounter any bugs/issues or have any ideas please let me know on and I’ll see whats possible.

Ibara, Pinksweets and Muchi Muchi Pork all have existing debug modes that can be used for practice. I do not plan to make any patches for them.
