- NEWS:
- - Modified memory map, now it has only 1k of RAM mapped on 8k Slot
- - Modified I/O map, now it is handled as on a real ColecoVision:
- The I/O map is broken into 4 write and 4 read ports:
- 80-9F (W) = Set both controllers to keypad mode
- 80-9F (R) = Not Connected
-
- A0-BF (W) = Video Chip (TMS9928A), A0=0 -> Write Register 0 , A0=1 -> Write Register 1
- A0-BF (R) = Video Chip (TMS9928A), A0=0 -> Read Register 0 , A0=1 -> Read Register 1
-
- C0-DF (W) = Set both controllers to joystick mode
- C0-DF (R) = Not Connected
-
- E0-FF (W) = Sound Chip (SN76489A)
- E0-FF (R) = Read Controller data, A1=0 -> read controller 1, A1=1 -> read controller 2
-
- - Modified paddle handler, now it is handled as on a real ColecoVision
- - Added support for a Roller Controller (Trackball), enabled via category
- - Added support for two Super Action Controller, enabled via category
-
- EXTRA CONTROLLERS INFO:
-
- -Driving Controller (Expansion Module #2). It consist of a steering wheel and a gas pedal. Only one
- can be used on a real ColecoVision. The gas pedal is not analog, internally it is just a switch.
- On a real ColecoVision, when the Driving Controller is enabled, the controller 1 do not work because
- have been replaced by the Driving Controller, and controller 2 have to be used to start game, gear
- shift, etc.
- Driving Controller is just a spinner on controller 1 socket similar to the one on Roller Controller
- and Super Action Controllers so you can use Roller Controller or Super Action Controllers to play
- games requiring Driving Controller.
-
- -Roller Controller. Basically a trackball with four buttons (the two fire buttons from player 1 and
- the two fire buttons from player 2). Only one Roller Controller can be used on a real ColecoVision.
- Roller Controller is connected to both controller sockets and both controllers are conected to the Roller
- Controller, it uses the spinner pins of both sockets to generate the X and Y signals (X from controller 1
- and the Y from controller 2)
-
- -Super Action Controllers. It is a hand controller with a keypad, four buttons (the two from
- the player pad and two more), and a spinner. This was made primarily for two player sport games, but
- will work for every other ColecoVision game.
