This is a very simple and tiny IPS patch, all it does is correct the colors for McLaren to resemble the white/red paint job they used in the early 90s, in the SEGA Arcade version the white/red colors were correct, but the Genesis/Megadrive port got a yellow/red version of the car which this patch fixes.

The changes should be evident in all modes:

• Super Monaco GP
• World Championship
• Team / Rival browser

Williams/Millions will also get a little bit of white as the car livery had more more white and blue than yellow.

The rest of the ROM remains unchanged for those who prefer accuracy & purity over eccentric color mods.

If you want to try this yourself, using a HexEditor search for all instances within the ROM for the following Hex Code:

00 EE 00 88 (Original Yellow Color for McLaren)

Change it to: 0E EE 0C EE (Modified White Color for McLaren).

After that, don’t forget to fix the checksum and you should be good to go!
