0.57 [Jarek Burczynski]


TODO:

* Dump M68705 MCU


WIP:

- 0.149u1: Modernized the buggychl_mcu device [Osso].

- 0.145u8: Phil Bennett removed some obsolete size members from msisaac_state (includes\msisaac.h).

- 0.140u2: Atari Ace take some driver_device classes of 40love/bking/buggychl/msisaac (common code in machine\buggychl.c) that cover multiple drivers and split them so that each driver gets their own driver_device class. In most cases, these drivers got entangled because of audio/mcu code that was shared between multiple drivers.

- 0.135u3: Fabio Priuli added shared driver data struct to Buggy Challenge and Metal Soldier Isaac II (they use the same MCU emulation).

- 0.131u1: Angelo Salese merged memory maps in the Metal Soldier Isaac II driver.

- 0.69a: Jarek Burczynski removed analog input definition and encoded it directly from Joystick input in Metal Soldier Isaac II. Changed Dial input to 8-way Joystick.

- 29th May 2003: Jarek Burczynski improved the MCU simulation in Metal Soldier Isaac II to mimic the original hardware better.

- 0.68: Jarek Burczynski and Angelo Salese added Metal Soldier Isaac II (Taito 1985).

- 4th May 2003: Angelo Salese submitted MCU simulations to The Legend of Kage and Metal Soldier Isaac II.

- 0.57: Jarek Burczynski added Metal Soldier Isaac II (Testdriver). TODO: Sprites are probably banked differently (no way to be sure until MCU dump is available). TA7630 emulation needs filter support (characteristics depend on the frequency). TA7630 volume table is hand tuned to match the sample, but still slighty off.

- 21st October 2001: Jarek Burczynski sent in the Metal Soldier Isaac II driver, which is unplayable due to a missing MCU dump.

- 18th September 2001: Jarek Burczynski fixed Metal Soldier Isaac II sound CPU interrupt problem.

- 14th September 2001: Jarek Burczynski sent in some preliminary screenshots of Metal Soldier Isaac II.

- 23rd May 1999: J-ROM dumped Metal Soldier Isaac II (c)1985 TAITO.
