I've got a couple of Entex Space Invaders that have the COP 444L, but there's a teardown on youtube showing one with a 28-pin TI chip, MP1211.

Space Invader 2 included in Entex Select-A-Game is very similar to the standalone Space Invader so they might be using the same chip.

I think the Led Sports games are a completely different beast though, there are a few cheap on ebay right now, I'd buy one just for the sake of checking it out, but the overseas shipping costs the seller is asking is just ridiculous. Most of these end up not selling at all from what I've seen lately.

I don't mind picking some up if they are cheap enough. Any suggestions?

This one was already relisted because it didn't sell so probably can be bought for the initial bid value:

Others:

Right now most of the cheap stuff are the Baseball games, but normally these games end up selling cheap or not selling at all when they come up for auction.

If you are in the US I'm fine paying for a couple of those if you want to have a look at them, just don't want to buy them myself as like I said the shipping costs here are ridiculous (4 to 5 times what I'd pay for the actual game) and I'm not interested on keeping the games anyway it would be for dumping purposes only.

BTW since it hasn't been mentioned here yet, Kevtris is on a roll. He figured out how to dump NEC ucom-4 42-pin devices (upd55x PMOS and upd65x CMOS, used in many VFD games from 1979-1984), and figured out (with Sarayan's help both of them figuring out most of the opcodes since these were not documented anywhere) how to dump Hitachi hd3880x 4-bit mcus, also used in VFD (and maybe LED?) games.
Both of these types can now be dumped without decapping using the test modes and/or test code built into the chip.

Being able to dump stuff non-destructively is always good when the target is 35-years-out-of-production games, since we can resell them afterwards.

OK, I bid on a couple of those. I'll see what chips they have and let everyone know.

Every time I read Kevin's stuff, it makes me realize how inefficiently I use my time.... That guy zooms through projects!

Beyond reselling the games, I feel bad destroying the chips if we already have die shots. And reading them electronically is much more elegant than blowtorching them!

I finished Bank Shot emulation yesterday. It's almost the same hw as Split Second, so I've put it in the same driver. opla and mpla are identical.

As usual I did also double check the rom for errors, but found none =)

Cool! I improved my ROM transcription code a bit, so it's probably catching a few more mistakes. I still manually check each bit as well, but that gets pretty tiresome, especially with these 4K chips.

I put some info about Total Control 4 on my TMS1400 page- www.seanriddle.com/tms1400.html, but I won't have the ROM dump or the full hardware description until next week at the earliest.

I just picked up Entex Electronic Baseball 3.
