Today. MAMEDEV coders Aaron Giles and Luca Elia have posted news regarding their codings for MAME. The following is a summary of these MAMEDEV’s work:

Luca Elia:

• Touch Master

I rewrote the skeleton driver for the Touch Master games by Midway. These are bartop arcade games, featuring many different mini-games.

I emulated the older titles, with a 68000 CPU, where the graphics are drawn by a blitter with access to a double buffered display. Later on (I’m told) they switched over to PC’s.

Player input is through a pressure sensitive touch screen (you can hover as well as press). That is not emulated correctly at the moment: the touch screen controller is declared not working at the boot. It then usually works well in game, but tends to go haywire for a while and sometimes it does not recover at all (you have to reset).

Let’s start off with the original, Touch Master (1996):

Then we have the third installment of the series, Touch Master 3000 (1997):

Notice the graphics corruption, due to a bad rom.

The fourth chapter, Touch Master 4000 (1998), is protected and does not work yet. It goes this far:

Thanks to ANY and NAZ.

I Think This One Is Going To Be Slow…

In a fairly typical move, I’ve blown off all my other projects to look at something shiny. There’s some decent progress, but any textures that aren’t coplanar with the screen are clearly quite wonky. In fact, it’s driving me a bit batty at the moment. At least it is working enough to parse the model data, and you can watch the intro with its rotating camera and rain effects (see last picture — it looks better in motion). There is still a ton of stuff that I don’t yet understand. Having a PCB would be very handy (not only for this but for weeding out the remaining TMS32031 math bugs). Anyone got one they want to loan me for a few months?
