RGB_Gamer Posted November 12, 2012 Share Posted November 12, 2012 Anyone know if this is possible? There doesn't seem to be any other way other than a Cuttle cart 2 which seem to be too hard/expensive to find. Quote Link to comment Share on other sites More sharing options...
OldSchoolRetroGamer Posted November 12, 2012 Share Posted November 12, 2012 Doubt it highly since I have never seen such a thing discussed and it would be big news around here, it would also likely boost the value of SuperChargers. Quote Link to comment Share on other sites More sharing options...
alex_79 Posted November 12, 2012 Share Posted November 12, 2012 Nope. At the moment the only other option other than the CC2 is to mod the console with the DevOS and have some ramcarts built. Since the software is dos based and a parallel port is needed for the connection you would probably have to use an old pc for the purpose. Or you can wait until the H2 is released..

+bcombee Posted November 12, 2012 Share Posted November 12, 2012 Yeah... the 7800 hardware locks out access to the MARIA chip once TIA registers are accessed, so you can't have a 2600 game that uses the 7800 capabilities. In order to unlock those parts, you have to go through the on-board ROM which does the encrypted signature check on the game cartridge ROM.

In order to unlock those parts, you have to go through the on-board ROM which does the encrypted signature check on the game cartridge ROM. Not exactly. The 7800 BIOS attempts to determine if a 2600 cart or a 7800 cart is plugged in. If a 2600 cart is detected then the 7800 is locked into 2600 mode (until the next power on cycle) and the 2600 cart's reset vector is called (there is some other checking stuff as well which I won't bore you with ). If a 7800 cart is present then its signature is validated on an NTSC machine (PAL doesn't do the check due to export restrictions back in the day) and the 7800 carts reset vector is called. Its the 7800 game that locks the console into 7800 mode. Quote Link to comment Share on other sites More sharing options...
iesposta Posted November 12, 2012 Share Posted November 12, 2012 The Supercharger only has 6K. I don't think any 7800 games are that small. Ms. PAC Man is 16K. Unless 7800 code less than 6K is written, and a way is figured to throw the 7800 into 7800 mode, or a way is found to add more RAM to the Supercharger...

+Gemintronic Posted November 12, 2012 Share Posted November 12, 2012 I'm surprised no one has figured out a way to reset into 7800 mode after booting into 2600 mode. It'd make the SuperCharger and Harmony cart so much more useful Quote Link to comment Share on other sites More sharing options...

Jinks Posted November 12, 2012 Share Posted November 12, 2012 So if the 7800 was able to be modded you could use a hamony cart to play 7800 roms? If so what would it take? Maybe dumber question why cant the harmony have 7800 files loaded onto it? Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted November 12, 2012 Share Posted November 12, 2012 So if the 7800 was able to be modded you could use a hamony cart to play 7800 roms? No! Not the games from the back catalogue or any of the homebrews to date. If so what would it take? The H2! . The signals A13, A14, A15, PHI2 and R/W# are missing on a 2600 cart connector.

Jinks Posted November 13, 2012 Share Posted November 13, 2012 (edited) Oh i thought the carts were the same but programmed different. (look the same) But the 7800 has extra connectors on the cart. So it would take a h2.. Thanks for taking the time to answer my dumb question! But it clears that up for all us who wondered..

LidLikesIntellivision Posted November 13, 2012 Share Posted November 13, 2012 Then why the harmony and supercharger would be more useful with a hardware mod for the 7800? Maybe a super cartridge for 2600 advanced games but it isn't yet 7800? An unique console between 2600 and 7800?? I'm surprised no one has figured out a way to reset into 7800 mode after booting into 2600 mode.
