[mspacman]+ Starting Level Update. Start at higher levels, play upside down mazes & the 255 Kill Screen & Game Moves For

Post by pac_man_fan2 »

The existing code didn't handle higher level starting points, ghost blue times were off, game crashed, overflow this and overflow that. So I fixed it!

Can start the game up to 140, past 140 the game would crash, so I added partial code to fix the crash so you can play the upside down mazes, and the level 255 split screen. Addiontally, can leave this cheat ON or OFF and the game will progress to the next level. It's no longer limited to the level selected.

This code supports: mspacman, mspacmat, msheartb, mspacmnf, pacgal2, mspacmancr

Code: Select all
