0.100u3 [Pierpaolo Prazzoli]


Artwork available


WIP:

- 0.171: Vas Crabb fixed TMS3615 clocks in Laser Battle, Guillaume Tell Overture is recognisable again. Note: If demo sounds are enabled (using DIP switches), background music is played every sixth time through the attract loop. Fixed inadvertently swapped TMS3615 organ chip clocks (fixes music) [Vas Crabb].

- 0.169: Make Lazarian playable: Decoded PLA bitstream and use for video mixing. Documented colour format and make up usable colour values. Implemented shell and area effects. Use proper video timings - yes there is blank space on the right. Added PLA from Lazarian to Laser Battle as bad dump as it's needed now. Yes it's impossible to get black because there's no LSB for blue. Colours are still wrong, but at least it's only the intensities now. Better layer alignment. Added comments. Fixed inputs, P2 controls and all DIP switches are usable now. Support cocktail configuration (set in Machine Configuration). Fixed conditions for latching sound data. Confirm DIP switches, use derived machine configs. Added stuff from manual [Vas Crabb]. Changed visible area to 736x247, VSync to 50.541416 Hz and TMS3615 sound clock speeds to 125000 Hz and 250000 Hz. Added dipswitches 'Infinite Lives', 'Difficulty', 'Bonus Life' and 'Coin C'. Added 'Cabinet' configuration.

- 0.150: Added 3x Signetics 2636 sound.

- 0.146u1: Some cleanup [hap].

- 0.136u1: Quench fixed massive slowdown in the Laser Battle driver.

- 0.135u4: Fabio Priuli fixed all sets in drivers using S2636 video chip.

- 0.135u3: Fabio Priuli added driver data struct and save states to Laser Battle driver. Converted Signetics 2636 video chip to be a MAME device and updated drivers using it accordingly.

- 0.129: Aaron Giles fixed a few out-of-bounds errors revealed by randomly initializing auto_malloc() memory. These would manifest themselves as difficult-to-reproduce crashes on some systems. Affects Laser Battle and other drivers.

- 0.111u6: Zsolt Vasvari and Derrick Renaud rewrote the SN76477 emulator from scratch. The main difference between the old one and the new one is that it is based on measurements from a real chip. Also the emulator is fully analog, meaning that timings/frequencies, etc. are based on voltage levels. This gives a much more true-to-life emulation where the weird behavior of the real chip comes emulated for free. The code itself is also a lot simpler and more understandable.

- 12th November 2006: Mr. Do - We have Lazarian, thanks to scans by Aaron Giles, on loan from Tim at ArcadeCollecting.com and cleanup by Ad_Enuff.

- 0.107u2: Changed S2650 CPU1 clock speed to 3579545 Hz. Replaced the 2x TMS36XX with TMS3615 (250000 Hz + 500000 Hz). Changed VSync to 50Hz.

- 0.105u4: Aaron Giles converted PLD for clone Lazarian to the new binary format. Added pld lz82s100.bin ($0).

- 0.103u4: Pierpaolo Prazzoli fixed Laser Battle/Lazarian - Game now playable. Added new cpu1 rom ($3800) and 82S100 prom.

- 0.100u3: Pierpaolo Prazzoli added 'Laser Battle' (Zaccaria 1981) and clone Lazarian.

- 21st September 2005: Pierpaolo Prazzoli - Laser Battle (Zaccaria 1981) is playable but some enemies' shots are invisible due to wrong colors (prom hasn't been dumped yet). Sound is missing, but schematics are available, so maybe someone can add it.
