So far, the AA-016 and AA-017 MCUs have been dumped successfully. At least two Great Swordsman boards have been seen with a UVEPROM-based D8741A-8 MCU for AA-013 at 9.5A. This suggests the developers made some last-minute change to the code that only the main CPU. It appears that during development, the developers worked with three copies of what became the AA-016 MCU. Protection code was added to the I/O MCU program, and this became AA-017. At this point they intended to use two copies of AA-016 for communications, and one AA-017 for I/O. It turned out that some last-minute change was required for the master CPU, but it was too late to order new mask ROM MUCs. This resulted in the use of UVEPROM parts for AA-013. There are problems with sound. Many effects aren't playing or are cut off almost immediately. It's not clear why - possibly due to some of the I/O that isn't understood. The audio CPU seems to have some unmapped peripheral(s) around $FEB0. +-----+-----------------+-----------------+----------------+ | Pin | AA-013 | AA-016 | AA-017 | +-----+-----------------+-----------------+----------------+ | P10 | to AA-016 P10 | to AA-013 P10 | P1 right | | P11 | to AA-016 T1 | to AA-013 T1 | P1 left | | P12 | unknown | DSW A 3 | unknown | | P13 | unknown | DSW A 4 | P1 lower | | P14 | unknown | DSW A 5 | P1 raise | | P15 | unknown | unknown | P1 middle | | P16 | unknown | unknown | 1P start | | P17 | unknown | unknown | 2P start | +-----+-----------------+-----------------+----------------+ | P20 | DSW C 1? | DSW B 1? | P2 right | | P21 | DSW C 2? | DSW B 2? | P2 left | | P22 | DSW C 3 | DSW B 3 | unknown | | P23 | DSW C 4 | DSW B 4 | P2 lower | | P24 | DSW C 5 | DSW B 5 | P2 raise | | P25 | DSW C 6 | DSW B 6 | P2 middle | | P26 | DSW C 7 | DSW B 7 | coin counter 1 | | P27 | DSW C 8? | DSW B 8 | coin counter 2 | +-----+-----------------+-----------------+----------------+ | T0 | serial clock | serial clock | coin chute 1 | | T1 | from AA-016 P11 | from AA-013 P11 | coin chute 2 | +-----+-----------------+-----------------+----------------+ ************** * AA-016 MCU * ************** The AA-016 MCU program is divided into several parts, each entirely contained in a single program page. The initialisation/self test, mode selection, and the main loop of the communication mode are in page 0; the subroutines implementing communication mode are in page 1; the input/coin handling main loop and host communiction code is in page 2; finally, the subroutines that implement coin handling are in page 3. This suggests componentes were assigned to different developers who were each given exclusive use of a page to simplify integration. There was insufficient space in page 3 for the program checksum fragment, so the coin handling subroutines are not checksummed, despite plenty of zero- filled space elsewhere in the ROM. The clock inputs for the MCUs are unknown - the values used are taken from gladiatr, where a superficially similar arrangement is used. It would be good if we could get frequency measurements for all the clock inputs: * Master clock input to each MCU on XTAL 1 (DIP pin 2, PLCC pin 3) * Serial clock input to communication MCUs on T0 (DIP pin 1, PLCC pin 2) Communication between MCUs is working - the handlers for parity error ($187), premature end of data ($194) and excess data bits are not being hit. This confirms that the MCUs are synchronising correctly and the serial clock is not excessively fast in relation to the MCU core clock. The communication MCUs transfer data bidirectionally on their P10 pins which are tied together. An MCU indicates that it is sending data by pulling P11 low. This is connected to T1 on the other MCU. The data clock is supplied to both communication MCUs on T0. Outputs are set after detecting a rising edge on T0, and inputs are read after detecting a falling edge on T0. A frame consists to five bytes sent LSB first. Each byte is followed by an odd parity bit. Useful addresses for debugging communication: * $12A: Function for sending a frame from $21..$25 * $159: Function for receiving a frame to $29..$2D * $187: Receive parity error * $194: Premature end-of-data * $199: Excess data AA-016 P15, P16 and P17 seem to have some effect, although it's not clear what they're supposed to do. Tying them low during startup prevents the sub CPU from correctly programming the I/O MCU. It's not clear whether pins corresponding to unused DIP switches have some other purpose. Fake DIP switches have been included to make it easier to mess with some of the unknown I/O. ************** * AA-017 MCU * ************** The AA-017 MCU program is divided into several distinct parts, each contained within a single page. The initialisation/self test and mode selection, the subroutine for receiving configuration, and an unused subroutine for sending a negated program byte to the host are in page 0. The subroutines that implement coin handling are in page 1. There are three input handling and protection programs of increasing of increasing complexity in page 2 and page 3. The host selects the input handling program to use with the high nybble of the first command. The subroutine for receiving configuration from the host is identical to the one in the AA-016 MCU besides being shifted to a different address. The entire content of page 1 is identical to page 3 in AA-016 besides being shifted to a different address. This MCU does not contain program ROM checksum code, so there is no way to verify the integrity of the program. After the self test and initialisation complete, the MCU waits for a command from the host and checks the high nybble. If it is 0x6x, the program at $200 is used; if it is 0x5x, the program at $23C is used; if it is 0x4x, the program at 0x300 is used; any other value will be ignored and result in the MCU waiting for another command. Great Swordsman uses the simplest input handling program which starts at $200 (beginning of page 2). This is similar to the input handling program in the AA-016 MCU with the addition of a call to a protection subroutine at $3CA added to the beginning of the main loop. Lack of the protection code in AA-016 causes the game to register credits unreliably if AA-016 is used in place of AA-017. The values stored at $29 and $2A are used by the protection code. The I/O MCU handles rejecting coin pulses that are too long or too short and converting coins to credits. The duration is measured in terms of rate that the sub CPU polls the MCU at. The minimum coin pulse duration is always two polling periods, while the maximum is programmable. The coins/credit settings for each coin input are programmable, but only the first one can be set with DIP switches (the second one is always set for 1 coin/1 credit). During the setup phase, the sub CPU writes setup instructions to the I/O MCU's control port. Each byte has an instruction in the high three bits and a value in the low five bits. Instructions recognised are: * 0x00: Set coin 1 maximum pulse duration ($2E, default 6) * 0x20: Set coin 2 maximum pulse duration ($2F, default 6) * 0x40: Set coin 1 coins per credit ($35, default 1) * 0x60: Set coin 2 coins per credit ($3D, default 1) * 0x80: Set coin 1 credits per coin ($33, default 1) * 0xa0: Set coin 2 credits per coin ($3B, default 1) * 0xc0: Set protection delay ($2A, default $08) * 0xe0: Swap nybbles and set protection time ($29, default $80) The protection delay is not used by Great Swordsman. The setup phase is terminated by writing a command to the I/O MCU's data port. The MCU return a data byte depending on the low three bits of the command: * xxxxxxx1 or xxxxx000: Credit flag and start buttons * xxxxxx10: Credit flag and P1 controls * xxxxx100: Credit flag and P2 controls The MCU keeps an internal credit counter ($2D). Each time the MCU receives a polling command, if the credit counter is non-zero it will be decremented and bit 7 of the response will be set; if the credit counter is zero, but 7 of the response will be clear. After terminating the setup phase, any byte written to the data port will cause the MCU to check the coin inputs, update the credit counter if necessary, and return the desired data. A byte written to the control port after the setup phase terminates causes the MCU to read a byte of program memory from page 2 using the received byte as the offset, twos-complement it, return it, and then immediately re-execute the previous command received on the data port. The protection routine sends a sequence of incrementing values to the host. The value is incremented by 1 or 2 if its most significant bit is clear or set, respectively. Every 256 iterations, the value will be replaced with a byte read from an incrementing offset in program page 3. The iteration count, protection value and offset all start at zero and persist between invocations of the protection subroutine. The protection subroutine runs for a configurable amount of time after each command is received. The I/O MCU indicates status via the user-defined status flags. It sets them to 0000 while waiting for a command, or 1111 while running the protection subroutine and processing the command. ******************************************/ #include "emu.h" #include
