Patches for UNIBIOS 4.0

• UNIBIOS created by Razoola
• Initial patch by ArcadeTV
• Multicart by Vortex

Patching

1. Obtain the UNIBIOS 4.0 ROM.
2. Use the BPS patch file to patch your ROM. I recommend FLIPS.

uni-bios_4_0_BackToMenu.bps

With this patch, keeping B pressed while soft rebooting from the in game menu will make the multicart boot on the menu.

uni-bios_4_0_PICKnMIX.bps

This patch enables PICKnMIX feature for a custom 161in1 cart, with some limitations:

• Always boots to PICKnMIX, even with a normal game cartridge.
• Works on MVS only (backup RAM used to store soft dips).
• No high score save.
• Tested on a MV1A only.
• Game list (titles and order) is hardcoded. The custom 161in1 cart must have been created with this one: uni-bios_4_0_PICKnMIX.csv.
• Use at your own risk!
