Pandora's Palace

0.36b6 [Manuel Abadia]


- Hold down P1+P2 START and reset game to enter test mode.


- On the first level, about half the pixels in the column near the bottom-left corner appear to be out of place and there are a couple of brown pixels on the ledge beside that column that should be on the horse statue's head on the other side of the screen. When you've played thru it to around level 6 or beyond, lose all your men, and start a new game, the pixels appear to be correct, the column appears correctly; most of the pixels on the entire screen have shifted. However, there are usually some stuck pixels (see the second linked screenshot, near the left bottom corner there is a brown line that didn't disappear). This usually gets stuck during stage transitions, when the pixels shift off the screen, and correct themselfves (disappear) a few levels later: save state (taken after a long game has been played, with pixels now displaying correctly/you can start a new game with it and the pixels are in place). I should also mention that every once in a while, a sound will get "stuck" on for a moment, doesn't sound correct to me but I suppose it could be because the hardware was so limited. pandoras058gre Smitdogg


- 0.37b14: Changed the M6502 CPU1/2 clock speed to 3072000 Hz, Z80 CPU3 to 1789750 Hz, I8039 CPU4 to 477266 Hz and AY-8910 to 1789750 Hz.

- 20th March 2001: Nicola Salmoria improved the sound in Pandora's Palace.

- 28th March 2000: Manuel Abadia added cocktail support to Baraduke, Metro-Cross, Gaplus and Pandora's Palace.

- 0.36b10: Changed M6809 CPU1/2 clock speed to 3MHz.

- 0.36b9: Changed M6809 CPU1/2 clock speed to 2MHz.

- 0.36b7: Changed AY-8910 clock speed to 4MHz.

- 0.36b6: Manuel Abadia added Pandora's Palace (Konami/Interlogic 1984). Issues: Press 1P and 2P together to enter test mode. There is an empty space ($4000-$5fff) on the CPU A. That space probably is used for debugging purposes on the real thing. The code checks that memory location, and if a ROM is present, it starts to execute code from that ROM. The AY-8910 has a timer or something like that on port B. I've managed to make it sound, but it's not 100% accurate.

- 21st September 1999: Nicola fixed colors, scroll and priorities in Pandora's Palace.

- 19th September 1999: Manuel Abadia sent in a driver for Pandora's Palace.
