The board is a different layout to the one above, here’s how I wired up the Voltage Regulator I recently converted a Super Famicom Shining Scorpion to be a PAL copy of Super Mario RPG. Very big thanks to Midari at who has shared some really interesting projects and PCB designs. Soldering ground for the Voltage Regulator needs a very hot soldering iron, if you are having trouble then you could get GND and/or 5v from elsewhere, the capacitor in the bottom left of the board is a good place, labelled C1, and it’s clearly marked showing which is positive. You could of course just use a couple of pieces of wire if you find that easier! I strip about 1cm from the end of a piece of wire (this is kynar), then mark how long each segment needs to be and use a pair of wire cutters to cut the wire coating and push it along to make the gaps. I forgot to mention linking the legs up and then soldering them to the Voltage Regulator. I decided to scrape away a bit of coating to give a bigger soldering points. Spec sheet for the Voltage Regulator, a very common model on eBay I’ve also cut off the middle leg and straightened the tab out so that they don’t touch the cart board (although that’s probaby overkill on my part), the tab is also 3.3v output. #Super mario rpg rom freeSoldered the chip in place (much like I soldered the Saturn Region Free BIOS), I’ve also added some solder onto those lifted legs, ready to wire them up.įor the Voltage Regulator, you need to feed it 5v and Ground, there’s a very convenient spot nearby the EEPROM so use that. I did read elsewhere that you could use a Voltage Divider though which I’d never heard of before, but sounds interesting.Īnyway, I use the pin method to remove the old Maskrom.īent up legs 1, 23 and 33 which are to be linked up to 3.3v I used a SMD 3.3v Voltage Regulator to power the new EEPROM. I can’t better the guide on, so here’s a few photos and notes of mine as I’m building it. BUT, it’s always worth contacting Bad_Ad84 for various chips etc :-) I got the 29元211 EEPROM from buyicnow, I sent them the file to be programmed (you have to make sure the ROM file has no header – it should be exactly 4,194,304 bytes and not byteswapped). It’s quite time consuming doing it that way, all those wires to cut, strip, tin, solder :-( So when I saw a different guide on I was curious to give this a go too. I let Chrome translate the page for me :-) I did one of these a while ago, using a 27C322 EPROM after seeing a guide about making a French Translation on Ultimate-Console. I wanted to try this game out, and fancied trying to convert a Japanese cart so that it was English. It’s a bit text heavy though, hence the American SNES version demands a higher price. Note: Be warned that Hard mode is insanely hard, and it is highly recommended to play Normal first.The cheapest source for Super Mario RPG is probably a Japanese Super Famicom copy of the cart. It is not recommended to try to switch between versions in the middle.
