I'm a big fan of consolized arcade systems - especially cart based systems. I used to have a consolized Atomiswave and it was nice enough. one system I've always wanted to have 'consolized' is the sega titan st-v arcade board. the idea of having it placed in a shell and saturn games being played from a cart the way they where before the 32bit era always seemed damn cool. this is a non issue - it is possible - what I wanted to know is if it would be possible to transfer saturn games to st-v carts. I'm guessing not at this point - the st-v hasn't been emulated right? but would it be possible in theory? consolized st-v+saturn library on cart - too cool for school.
It's possible but it won't happen. It would take immense skill to get even the smallest of Saturn games reworked for it and even then you'd would need to make your own STV playback device. You must also think about FMV and CDDA which is worked into almost every Saturn game. My bet is that only homebrew will ever run on it since your average Saturn game is 400MiB and the max ST-V game is 48MiB.
Telling by the title, I thought I would hear an alien abduction story... Too bad I'll reply that this is as complicated as simple as it sounds. In other words, I would second what Calpis stated above, you need to basically cripple the software and you still need a lot of work, engineering-wise.
It isn't, the memory mapping is different. Somebody at SegaXtreme planned on making an ST-V->SS cart converter, but ran into this (and other) issues.
Well, he just posted his idea on the SX boards stating he had already found a manufacturer, but no real design. However, he appears to have abandoned the idea after somebody posted about the above problem.
