http://www.ebay.com/itm/TV-Baseball-/311505438633?hash=item48872bc7a9 -- is it some Cassete Vision-based standalone game? or something unique?

TV Baseball was released as a standalone game before Cassete Vision even existed. It was then re-released as a CV cart (Cart #2), I believe it's the exact same game, but there could be some slight changes I guess.

Yes, both the "TV Baseball" and "Baseball" cartridge are the same game, also same for the "TV Vader" and "Battle Vader" cartridge (same chips).

If plgDavid is up to it, i can lend him soon all the cartridges as i'm waiting for the "Elevator Panic" cartridge to arrive so i'll have the entire library ready to be dumped.

Same as for the Hanimex HMG-7900, i'm waiting for the last game (Raging Turtles) to arrive soon and i'll have also the entire library for this game system.

Oh and almost forgot, i can also lend the "Epoch TV Vader" as this one is completely dead so no problem to "cut in half" the chip or give it hell! (lol!)

Nice, I guess he won't be needing my games after all smile
I'm really looking forward to see if any progress can be done on these, I think the HMG-7900 carts will be easier to dump than the CV ones at least judging by the ones I looked inside, not really sure about what's inside each cart since it seems to vary a lot more than in the CV.

I think plgDavid can't dump CV carts as he seems to have sent one to LN a while back. Hopefully someone will be able to figure a way to dump these in a non-destructive way, for most games of the system this isn't a big deal though since they are pretty common.

Dumping the TV Vader would also be interesting, I was actually considering buying that TV Baseball which sold cheap, but ended not being around at the time the auction ended.
This isn't a rare game anyway, so there will be plenty of chances to get one if we need it.

I'm waiting for one of them to be decapped (the one I sent to LN), then we might find out a way to do the others without such invasive measures.

I'm trying to get the package sent to sean but having trouble finding the scv and s&l boards. I think I know where they are now, though.

Edit: nope. not there. I'm driving myself up the wall looking for them, I think I will have to send this package without them.

Edit2: package sent.

@ssj: But before lending him the games, i'm still waiting for the last one to arrive and in the meantime, i'll A/V mod one of the game system and record videos for each game.

The difference between the HMG-7900 and the Cassette Vision is that the Cassette Vision uses "all-in-one" chips or aka dedicated chips with built-in program and for the HMG-7900, the D779C-300 is
also a "all-in-one" chip but can change the built-in program (in this case, the Chaser game) with other program cartridges. smile

So simply put, a Cassette Vision cartridge has a "all-in-one" dedicated chip and a HMG-7900 cartridge has only a PROM chip.

Well if Sean is interested on decapping one CV board some games are pretty cheap on ebay, there are a couple available for less than $10. I'll happily pay for one of those if needed since that board seems to be MIA.

I believe previous attempts have been done to dump CV games electronically without success, but there has been a lot of progress done lately with the electronic handhelds dumping so perhaps someone will manage to figure it out.
