Impaler_26 Posted May 13, 2007 Share Posted May 13, 2007 Yeah! I finally found an Interton VC 4000 Emulator after looking for one since years! thunderstruck from the CCC Forum posted a link there and i thought you guys here might be interested in it too : Interton VC 4000 Emulator. At the moment there aren't many working Roms for download yet, so somone has to dump all the Interton Carts!! Quote Link to comment Share on other sites More sharing options...
Kurt_Woloch Posted May 13, 2007 Share Posted May 13, 2007 Yeah, I downloaded this too some days ago, along with the "software pack" for the VC-4000, and it occured to me that the pack only contains 2K games, which means that none of the more elaborate games are in there. Yet, in the "gaming guide", there are several 4K games listed as having been dumped, e.g. Backgammon, Boxing, Chess, Cockpit, Draughts, Golf, Metropolis/Hangman, Motocross/Dragster, Spider's Web/Monster man, Super Space, Winter Sports. Could it be that they're not included in the pack because the emulator doesn't support 4K carts for the VC-4000 yet? By the way, there seems to be some confusion about the processor speed of the VC-4000. I've also downloaded the book describing the Elektor computer, which says that the 2650 processor is clocked at 1,79 MHz, which is divided by 6 internally and thus would give a cycle duration of 3.36 microseconds. The book gives it by saying that the processor is able to execute 19 cycles per scanline, which is roughly the same, and is only a third of the amount of cycles a 6507 does in the Atari 2600. But other sources say the VC-4000's processor would be clocked at 4.47 MHz, and the successor of the VC-4000 is said to have its processor clocked at 3,59, which would be the double speed of the VC-4000. I wonder if that's correct and what of this is correct. Anyway, with the 2650 processor being that slow, this explains why the arcade game "Hunchback" looks as bad as it does, having choppier animation than the C-64 version, which doesn't make you wonder if you consider that the C-64's processor is over 6 times faster than the 2650 in the Hunchback machine (which is clocked at 895 kHz, thus a cycle would take 6.72 microseconds to execute there!)

Thomas Jentzsch Posted May 13, 2007 Share Posted May 13, 2007 Maybe this helps. BTW: MESS emulates the Arcadia too. Arcadia.zip 1 Quote Link to comment Share on other sites More sharing options...
+LS650 Posted May 13, 2007 Share Posted May 13, 2007 In case anyone is wondering what an Interton VC 4000 is (I know I was)... http://en.wikipedia.org/wiki/Interton_VC_4000 Quote Link to comment Share on other sites More sharing options...
Kurt_Woloch Posted May 13, 2007 Share Posted May 13, 2007 (edited) Maybe this helps. BTW: MESS emulates the Arcadia too. No, sorry, it doesn't help... the ZIP file you posted seems to contain only Arcadia ROM's. What's missing is a lot of VC-4000 ROM's (especially all who are longer than 2K). But you are right... MESS now emulates both the Arcadia and the VC-4000... and it's got the same graphics glitches on CIRCUS. :-) By the way, I've been wondering if a Tetris variant would be possible on the VC-4000, since it has been done on the Arcadia too. I think it's not too hard if you can live with the blocks being nearly 2 times as wide as they are high, and if it's possible to read from the object shape memory locations... otherwise, good luck, you only have 37 bytes of RAM! On the other hand, on the Elektor computer it would be doable for sure, since you have more RAM there. And the expanded version working with the expansion board could even have pretty good music (think about it... they equipped it with TWO AY-3-8910 PSG's, giving it 6-voice sound which makes it even surpass the Atari ST (which had only one of those)).

Hm.. it's possible that the Emulator doesn't support 4K carts yet, all the roms are only 2K and after all it's an Arcadia 2001 emulator that also works with VC 4000 Roms and it was not especially made for VC 4000 Roms. I didn't have much time to try it out yet, just checked out some of the working Roms... but i had a good laugh as i saw "Laser Attack", a Laser Blast clone that's even worse than the 2600 original But nevertheless it's a good start.... I hope support for larger VC 4000 Roms will be added, i'm curious to check out a few games i didn't have like Hyper Space, Winter Sports and Super Space.

I'm still using MESS 0.88b Quote Link to comment Share on other sites More sharing options...
