What does it run? Everything and anything. 4, 8, 16 mbit eproms. The superfx chip is the gsu-2-sp1. I installed a 512k ram chip that overclocks faster than other ram chips and restored the address line needed to get 512k of ram instead of 256k. There's a four pin header on the back with connectors for 5v, ground, the original 21.4 mhz clock (pin 1 of the cartridge connector) and the clock line that feeds directly into the superfx chip if I ever feel like plugging in an oscillator for overclocking. This cart plays super fx original roms or romhacks of any size up to 16 mbits at either default or various overclocked speeds. The save battery has been socketed for easy swapping. The eprom socket is standard 4 / 8 mbit eprom wiring, the extra pin connector is the extra address line needed for a 16 mbit adapter.
Show us the other side of the board, otherwise it just looks like a Yoshi's island gamepak, running Yoshi's island modified rom, with wires and headers hot glued on(no offense). But hey pretty darn cool! Now only if you can attach a fpga and use it as an interface to select roms from an sd card, maybe we could all have a flash cart that actually plays SFX games. Tutorial and schematic would be choice, if you feel like sharing.
Hes just ran wires from the pads on the PCB to a socket. There is no magic here, I dont see any reason why he would fake it - there is no point, its not difficult and been done before. If you want to play another game, you program another chip and replace the one in the socket. Or, if you have a larger EPROM, put 2 games on 1 chip and add a switch on the last address line. The crystal part hasnt, but we all know how I feel about that anyway. He has just done this: http://nintendoallstars.w.interia.pl/romlab/lorom1.jpg http://3.bp.blogspot.com/-Aw-ivfPlu...DbE/khcTnl5kHnw/s1600/2013-04-29+23.56.42.jpg http://kogami02.free.fr/Divers/cartouche_test_3.JPG But using a superFX cart (and using wire to solder to the SMD footprint and swap the few differences in the pinout to standard eproms) Edit: infact, here is more info as bacteria made one last year too (and he likes to document things quite well) http://www.made-by-bacteria.com/forum/viewtopic.php?f=23&t=1635
Like he said it's all stuff that's been done before. I just wanted to build one that looks nicer, has the battery saving circuit, runs 16mbit games and can overclock all from the back of the cart. Basically a neatly built cart that does it all. I didn't take a picture of the front of the pcb because it's soldered straight into that socket with short wires. When I first made this thing I didn't plan on building it into a case. I don't see why someone would be skeptical about me wiring up a romhacked rom instead of a socket, not like wiring in a socket is any more difficult than swapping the maskrom. I'm not messing around with the multicart idea simply because each game overclocks to a different speed. It's better building stand alone carts. This cart is just something I built for easy testing / playing of romhacks and stuff that needs different clock speeds. ....yes *edit* Found a picture of the front of the pcb I took before I wired it into the case: This's pretty much everything wired up the same way as it is now, just without a case and having the oscillator soldered onto the wires instead of having it attached by a socket (only 3 wires needed).
I take it you've never seen any of Drakon's mods before... Everything he does is coated in at least 6 layers of hot glue. :biggrin-new:
Haha, I still like your ramchip soldering system in famicom carts I think it's better than using wires.
