Notes: Tetris - RAM 0xa0 and 0xa1 contain the ACD0 and AD1 values and player 2 controls if between certain values? probably read via serial (or ADC abuse?) Internal Test Menus: Tetris - hold P1 Down + P1 Anticlockwise (Button 2) on boot Space Invaders - hold P1 Down + P1 Button 1 on boot ABL Air-Blaster - none? ----------------------------------------------------- Flaws (NOT emulation bugs, happen on hardware): ----------------------------------------------------- rad_sinv: In QIX the sprites lag behind the line drawing, so you see the line infront of your player until you stop moving In Space Invaders the UFO can sometimes glitch for a frame when appearing, and wraps around at the edges (even if the hardware supports having higher priority tiles to prevent this, as used by Lunar Rescue, it isn't used here) Colony 7 has a typo in the instructions The fake 'colour band' effect does not apply to the thruster (and several other elements) in Lunar Rescue Enemies in Phoenix are rendered above the score panel The 200pt right facing bird on the Phoenix score table is corrupt Space Invaders seems to be using a darker than expected palette, there are lighter colours in the palette but they don't seem to be used. It's difficult to judge from hardware videos, although it definitely isn't as white as the menu, so this might also be a non-bug. (Uncertain - to check) ------------------------- airblasjs: This game is very buggy. The 3D stages are prone to softlocking when the refuel jet is meant to appear. 2D stages will zap you of your lives and then continues one by one if you die on a boss meaning if you have 2 continues left you'll be offered the continue screen twice while it drains you of your lives before actually presenting you with the Game Over screen. The manual claims you can't continue on a boss however this isn't true for the 3D stages, where the continue feature works as expected. Either way, this is a very crude way of implementing a 'no continue' feature on bosses if it isn't simply a bug in the game code that was explained away as a feature. Sprites clip on / off the top of the screen in parts - if you move your the player helipcopter to the top of the screen the top 8 pixels clip off too (not currently happening in MAME, probably need to take out sprite wrapping on y) Sprites wrap around on X too, if you move to the left edge you can see your shadow on the right etc. Sound sometimes stops working properly / shot changes for no reason. There's no indication of damage most of the time on bosses, some parts won't take damage until other parts have been destroyed, not always obvious. Very heavy sprite flicker (not emulated) Very heavy slowdown (MAME speed is approximate) */ /* Buzztime Trivia notes from Tahg (addresses based on base ROM, not cartridges) 300 Cursor Left 301 Cursor Top 302 Cursor Right 303 Cursor Bottom 3E5 Sent Command 3E6 Watchdog Counter 3E9 Active Player 3EA Sent Player Id/Incoming Byte 3EB Sent Player Button/Loop Counter 0-A Name E-F Score 44x Player 1 Data ... 4Fx Player 12 Data 509 Cursor index 515 Name on Enter name screen These read a byte, (aaabbbcc) MSB first on IO 5041.
