Home Page Forums MAME MAME TMS-09xx/1xxx thread (was New Dumps)

it looks like one bit was missing on the space invader 2 dump. The new dump has 1 more bit and more valid instructions. I will keep it desoldered until it's confirmed to work. This chip is interesting in that banks 0 and 1 are not accessible from code directly it seems. I have a debug mode that will do a "tree dump', chaining calls and jumps together to traverse the banks and discover new ones, using recursion. I have pasted the bank traversal below if anyone is curious what it looks like. The tree dump was the only way to dump these at first, until I discovered the factory test code that lets you dump any bank you choose. Unfortunately I forgot most of how it worked since that was 4-5 years ago. but the dumper still works fine.

Dumping data!

Could you post a link to it?
And yes it's 5 mini games. In multi-player, it will announce the winner at the end (the player with most points)

Space Invader 2 redump is good, thanks!

Can your dumper access all pages? In theory it's possible for a game to access the factory test mode data with the Pattern opcode.

Here you go:

I posted some good pics of the sound effects chassis thing. front, back, in the bag, and the paper instructions that came with it. there was a hang card closing the bag up but I don't have it.

There's also a short MP3 of it showing off some of the tones and the fadeout effect.

The new space invader 2 seems to work, but it "locks up" when the game ends. is this normal? there's a similar standalone version of the game and it seems to do this also.


http://blog.kevtris.org/blogfiles/H...s/RS%20Sound%20Effects%20Chassis%20Game/

it can. I use the factory test mode to dump every page regardless of it's used or not, or has a link via jump/calls.

Can you make out all the writing on the bottom? It's a Rev C board, so it seems like something that would have been in production if they had made 3 revisions to the board (although I guess the revision could have been before it was ever released...)

I see this number: 25-60032 Is that the full number? Can't tell if there's another digit under the button contact
And the writing at the bottom looks like TCI-A3H and something underneath it?

Kevtris said on IRC chat: 25-600321, REV C, TCI-A3H / 94HB
I checked the SAG Space Invader 2 manual, it says to turn the game off and on again at game over, so I guess it's normal

screenshot of Space Invader 2:


In MAME it starts upside-down by default, since most of the SAG games are played from the 'visitor' side. You can rotate it in video options.


and the Radio Shack pcb:

those 4 aren't dumped yet
