New clone: D2K Jumpman returns
- emulates Braze Technologies addon board - eeprom hooked up - implemented bank switching I am still unsure about whether this should be added or not. Interestingly, D2K shows a "(C) 1981 Nintendo" copyright message. Still, it is actively marketed. Putting this up for discussion again.

D2K Jumpman returns Notes
|
||||
=========================
|
||||
|
||||
This is a DKong/Hack combo using a Braze Technologies High Score Save pcb.
|
||||
This pcb will be placed in the cpu socket and the Z80 together with an
|
||||
additional 64K rom, a 74LS245, an eeprom and a pal/gal. It looks like the
|
||||
"encryption" was a conincidence resulting from an easy pcb layout.
|
||||
The pal is also used to switch A15 on and off. This is done in locations
|
||||
6800 and E800.
