Radica Games 6502 based 'TV Game' hardware
These use a 6502 derived CPU under a glob
The CPU die is marked 'ELAN EU3A05'
There is a second glob surrounded by TSOP48 pads
this contains the ROM
Space Invaders uses a 3rd glob marked
AMIC (C) (M) 1998-1 AM3122A
this is presumably for the bitmap layer on Qix
--
Known games on this hardware
Tetris
Space Invaders
ABL Air-Blaster Joystick
---
XaviX plug and play units almost always have a XaviX logo on the external packaging
while the ones for this driver (and SunPlus etc.) don't seem to have any specific
markings.
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)

/* Tetris (PAL version) has XTAL of 21.281370
Air Blaster (PAL version) has XTAL of 21.2813
what are the NTSC clocks?
not confirmed on Space Invaders, actual CPU clock unknown.
21281370 is the same value as a PAL SNES
game logic speed (but not level scroll speed) in Air Blaster appears to be limited entirely by CPU speed (and therefore needs to be around 2-3mhz
at most to match hardware) - a divider of 8 gives something close to original hardware
it is unclear exactly what limits the clock speed (maybe video / sound causes waitstates? - dma in progress could also slow / stop the CPU
and is not going to be 'instant' on hardware)
using a low clock speed also helps with the badly programmed controls in Tetris as that likewise seems to run the game logic 'as fast as possible'
there don't appear to be any kind of blanking bits being checked.
