Console Tapwave Zodiac

Name GuineaPig for Zodiac

Description GuineaPig is a freeware open source emulator of several consoles of the early to late 1980's and early 1990's, including the SEGA Genesis (Megadrive), the NEC TurboGrafx (PC Engine) the Sega Mastersystem and the Game Gear. GuineaPig is built up entirely from Charles MacDonald's excellent emulators including Genesis Plus, SMS Plus and TGemu.

As of the alpha 001 release, GuineaPig requires an OS5 high resolution device with an expansion media card. I will likely build a mode soon so it can run on low res OS5 devices like the Treo 600. Its possible I'll build a mode so it can run without an expansion card, but for now it requires ROM's to be on expansion media.

Memory requirements vary by emulation module; the Genesis module is the big boy; the SMS/GG and TG16 modules have much lower requirements!

A lot of memory is needed in these early releases of the Genesis module, so many older OS5 units won't be able to run it. But memory requirements are going down with each revision, so if you're running out of runtime RAM and getting errors, keep trying as new versions come out. (Remember, theres device runtime RAM and storage RAM. Its the runtime RAM thats small and we need lots of)

For example, the TH55 couldn't run the 001 version of the emu, but sure should be able to run the 004 version!

For now its a bit basic, but the app is yet young. You'll need to have an expansion card (SD card, memory stick, compact flash, etc) to use the emu.

Install GuineaPig.prc to your device (wherever you want it to be)
As of 006 and later, install any emulator modules you desire; genesis.emu for genesis, smsgg.emu, or pce.emu for example. (They go in /PALM/Programs/GuineaPig with your ROMs)
After running GuineaPig at least once, you can just hotsync .smd files over to your expansion card. (.bin and other extensions are not managed for hotsync due to potential conflicts, but will work fine in the emu!)
Note that you can use .bin or .smd for Genesis, .gg for Game Gear, .sms for Sega Mastersystem, and .pce for PCEngine (TurboGrafx16) games. You need the appropriate emulator module (.emu file) to run the games of course.
If you're confused about getting the files to your card, consider using a card writer (USB SD writers are cheap at your local computer shop), Card Export software, hotsync, rename-trick, etc. Use Filez or FileCaddy (both are freeware) to move it around and rename it if needed.
You put your cartridge game ROMs and emulator modules in this directory -- /PALM/Programs/GuineaPig
ROMs must (for now) be unzipped; so no .zip files!
Thats it. Just run GuineaPig :) Pick a ROM from the listing and hit Go!
