0.100u1 [Pierpaolo Prazzoli]


WIP:

- 0.129u6: Added dipswitches 'PIA0.A', 'PIA0.B', 'PIA1.B', 'PIA2.B' and 14x 'Unknown' dipswitches.

- 8th January 2009: David Haywood - I've been working with Roberto Fresca on some drivers lately. One that came to our attention was the 'Coinmaster' one, due to a recent dump of a Poker game running on that hardware. I was asked if I could take a look at the tile banking, and try to locate the palette, which was proving to be difficult to find. After some educated guesswork I ended up with the following (see screenshots). Turns out the game has a 1 bit per colour, 4 colours per tile palette stored with the tile data in ram, rather than a global palette which any tile can access. There are still a few things to be figured out, such as if it has brightness control on the colours (which would allow more colours) and if the extra ram that Super Nudge 2 and the Poker game have expand the palette in any way.

- 0.100u1: Pierpaolo Prazzoli added 'Trail Blazer' (Coinmaster 1987).

- 9th September 2005: Pierpaolo Prazzoli - I started to re-look at Coinmaster's trivia games: Quiz Master (1985), Trail Blazer (1987) and Super Nudge 2 (1989). They're really weird. They use a 46 x 64 tilemap with videoram starting at offset $240 and using the previous offsets as main ram. Also tile banking is strange. They use an attribute ram for every banking address bit they need (so in games with $400 tiles, they have 2 attributes rams with all the other 14 bits used and still unknown). I don't know if they have a hard-coded palette or if they use a strange paletteram format.
