PC-Engine Hardware Kits
Various pieces of hardware pertaining to NEC's PC-Engine/TurboGrafx-16. Maybe these will help with making games. I don't know.
MCGenjin Memory Mapper
Completed: 7/31/2011, Build Time: A day or two to write, a month to test!
MCGenjin is a memory mapper for the PC-Engine and TurboGrafx-16 which supports dynamic region switching.
Essentially, it can reverse the order of the ROM datalines under software control.
It also gives you 8MB of banked ROM, two general purpose chipselects, and fits inside a single Altera EPM7032LC44.
POF Files, VHDL Source, Equates/Documentation, and an example of starting up the console using the mapper are given below.

MCGenjin 4MB Plus DevCard
Completed: 10/25/2011, Build Time: A few evenings of tea and board layout.
This development card couples a MCGenjin Mapper with 4MB of Flash ROM in the form of a 29F032 (expanded to DIP form factor).
In addition to the region switching and memory mapping features given by MCGenjin, a FM1608B (8KB FRAM) and AS6C1008 (128KB SRAM)
are mapped to banks $40-$5F (MCGenjin-CS0) and $60-$7F (MCGenjin-CS1) respectively.
So the user has some handy nonvolatile storage for game saves, and room to breathe over the standard 8KB of RAM in the PCE.
The gerber files for the board are given in the ZIP file below, along with a new MCGenjin POF file.
If you plan to build one of these cards for yourself, please take care to use this POF file instead of the standard MCGenjin POF, as the pinout is customized for this board.

TurboBreak-16 Breakout Board
Completed: 9/16/2011, Build Time: Maybe an hour.
Mongo like big solderpoints.
