This is a program for NEC's PCE / TurboGrafx, etc. game hardware that emulates Nint*ndo's GameBoy system. Bear in mind that the PCE's CPU clock speed is not even twice that of the GameBoy, and that they both possess 8-bit CPUs (6502-like vs. Z80-like) with vastly different registers and instruction sets. So, yeah, it's a bit crazy to try to get a GB game running on the PCE in the first place, let alone hope for anything approaching actual speed.
Some Main Features:
- All CPU instructions emulated (no guarantees about accuracy!)
- No promises about speed. It's not fast.
- MBC1 cartridge mapper emulation, supporting cartridges <1 MByte in ROM / <192 KByte for CD-ROM version
- Basic sound emulation (frequency, volume sweep, wave channel and pulse/noise channels)
- DMG BG & sprite palette emulation, with separately adjustable palettes
- Background layer, scrolling, per-scanline scrolling emulated
- Window layer simulated but with some limitations
- GB sprites, both 8x8 and 8x16, tile-flipping.
- An options screen with plenty of controls to change speed/accuracy, enable/disable features
- Did I mention it was not very fast?
Requirements:
You'll need either a SuperGrafx, or the CD attachment for PC-Engine/TurboGrafx, due to RAM requirements.
The stock PC-Engine / Turbografx consoles have only 8 KB of main system RAM, whereas even the original B&W GameBoy had over 16 KB of RAM that needs to be stored and emulated somewhere. I've therefore made versions of Hu-Boy that use either CD-RAM from the PCE CD-ROM2 system, or the SuperGrafx's extra built-in RAM. So you can use a SuperGrafx plus ROM flashcart (recommended), or burn/emulate an ISO and run it from your PCE+CD-ROM2 system with Super System Card.
