Basil is a PET Emulator for Commodore 64, inspired by Jim Butterfield's One-Line PET Emulator shown in Robin Harbron's 8-Bit Show And Tell.
Basil emulates CB2 sound, both PET character sets, various keyboard models, shift key register and disables color control codes. Basil runs unmodified C64 KERNAL ROM and a patched copy of C64 BASIC in RAM, remapping many zeropage POKE's and PEEK's to corresponding C64 locations (such as cursor location, key buffer, memory pointers, USR function address).
Basil even adds that one extra space before each line number in LIST, just like PET does. First half of PET BASIC ROM is included as a memory image, because many programs check bytes in memory range $c000-$c3ff to detect PET ROM version. Oldest PET ROM has a different memory map that is not compatible with Basil.
Historical games (and those that are a little more complex than just text adventures) currently working include Bonzo, Android Nim, Bat, Bets, Blackjack, Checkers, Dungeon, Everest, Lander, Ambush, Capture, Racer, Lawn, Tank, Ouranos, Rescue, Star Wars Train, Pinball, Fogs, Space, Afo, Alligator 2, Jackpot, Debris, Ski, Volcano, etc. |
