CD Stupid Card 4.0
2015-3-29 (PCB), 2015-5-7 (Mapper)
This enhanced System Card features 512KB of ROM in a removable
DIP 39SF040 and 2MB of SRAM.
Featuring the new MC-Genjin CD - it supports a Super System Card 3.0
compatible memory layout, multiregion operation, and a special linear
mode which maps the card's lower megabyte of SRAM over the entire
HuCard address region ($000000 - $0FFFFF, MPR $00 - $7F).
The two indicator LEDs illuminate when an operating region has been
set (D1, Upper) and when switched into linear mode (D2, Lower).

||How to use the CD-Stupid Card's features in your own software.
||PCB Layout. Note the TSOP-II SRAMs must have pins 7, 8, 15, 16, 29, 30,
37 and 38 removed and the remaining pins curled under (similar to an SOJ)
in order to properly fit on their pads. I messed up the layout, my bad.
||Required electronic denizens.
||Verifies operation of MC-Genjin CD and both SRAMs.

||UPS Patch for expanding NEC's Super System Card 3.0 to support the
enhancements in the CD-Stupid Card, this can be helpful for developing
translation patches or new software.
