* The Japanese text on the Roads Edge network screen says : "waiting to connect network... please wait without touching machine"
|
||||
|
||||
ToDo:
|
||||
* clean up I/O / MCU communication
|
||||
* Buriki One / Xrally and Roads Edge doesn't coin it up, irq issue?
|
||||
* sprite garbage in Beast Busters 2nd Nightmare, another irq issue?
|
||||
* Samurai Shodown 64 2 puts "Press 1p & 2p button" msg in gameplay, known to be a MCU simulation issue, i/o port 4 doesn't
|
||||
seem to be just an input port but controls program flow too.
|
||||
* work out the purpose of the interrupts and how many are needed
|
||||
* correct game speed (seems too fast)
|
||||
* figure out what 'network' Road Edge needs to boot, it should run as a standalone
|
||||
* make ss64 boot (io return 3 then 4 not just 4) then work out where the palette is
|
||||
|
||||
2d:
|
||||
* scroll (base registers?)
