/******************************************************************************************************* coleco.c Driver file to handle emulation of the ColecoVision. Marat Fayzullin (ColEm source) Marcel de Kogel (AdamEm source) Mike Balfour Ben Bruscella Sean Young 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 On a real ColecoVision, when the Driving Controller is enabled, the controller 1 do not work because have been replaced by the Driving Controller, and controller 2 have to be used to start game, gear shift, etc.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. *******************************************************************************************************/ /* TODO: - Dina SG-1000 mode */ #include "includes/coleco.h" /* Read/Write Handlers */ READ8_MEMBER( coleco_state::paddle_1_r ) { return m_joy_d7_state[0] | coleco_paddle_read(machine(), 0, m_joy_mode, m_joy_analog_state[0]);
