SEGA ST-VE (Saturn/ST-V Enhancer)

Hmmm, interesting. Maybe it is for the best that a Game.com version of VF3 never comes to light. It would have been just as bad as the other Game.com games.

The VCD port is too limited in terms of access to the HW like MD unlike PCE which has an Ext. port as it should be. You need the main Saturn slot. As far as I know regarding VF3 there are rumors of two builds. One is a slot-accelerated GPU design by Core Design and one stock Saturn AM2 design which uses very low texture BGs. Of course Yu doesn't know about that. maybe b/c he was pissed that he was backstabbed with VF3 DC when getting VF3 SAT ready to ship?

The main problem with Saturn is communication between those chips and the amount of those stoopid chips. The bus-system is very limited. PS1 smokes Saturn like double in bandwith. So putting a second VDP1 in there would have meant some serious architecture reconstructuring and still you would not get double the output you hope for.

@lollyroger Madhouse, that is what Saturn is all about. On the other hand two steps away from Model 2/AM2 department we have a simple to program for "pedal to the metal" HW. Sega was not only too dumb to communicate with Sega of America, nope... they were even to dumb ato communicate with YU, that little guy who made Sega big.

PCE Ext port = card slot , you can build Ext port play card game or build card slot link to CD-ROM interface
MD Ext slot like card slot too, they did 32x on card slot , also you can build 32x on Ext slot

Saturn VCD card is decode VCD data map to Saturn video address to over layer out put on screen , it also did on ext slot .
so any hardware , just only map the video data to Saturn video address and joy pad address, it will look like real........

may be still think, ask you joke? ,with out talk video over layer. in real they still have other way did what they want, you can image SNES/SFC oem stuff "TRI-STAR" how it work, than you can image if TRI-STAR is n64/GameCube hardware .....


they use old school style let you feel is real XD

The VCD card slot is just not that useful for anything but it's design purpose though - yes, it has the EXBG lines that go to VDP2, and you can display video data through it - but the rest of the lines on the socket are connected to the SH1 in the CD controller and can't be directly accessed from the rest of the system.

The cartridge slot also gives you access to the EXBG lines - but it's also connected to the SH2 address and data buses and you can boot from it.

Here's a (likely mocked-up) cartridge shot from an old magazine:

Legit looks like a Game Gear cart

once layer the video and map Saturn controller io, is ok , user don't know super power top of add on hardware, the main util only did video output and controller
