Store

If you prefer, I have an Etsy shop set up to order from as well.

Here’s a very primitive “store” I’ve set up, for your browsing pleasure! This will be constantly expanding, and eventually I’ll start including parts that aren’t even mentioned in any of my tutorials, but are still handy. I have a huge pile of old parts that I’ve acquired that I need to get rid of – no one is going to use 1,000 Schottky diodes after all.

I’m also selling things on my newly created Etsy page, if you’re more comfortable going through that website instead of through me directly. Also, I believe Etsy will allow me to ship internationally, so if you’re here from outside the US, check it out! I’m still populating the store with all my boards but I have a handful up right now.

If you want to buy direct, send me an email at thepoorstudenthobbyist@gmail.com, let me know what you want to buy, and I’ll try to get back to you when I’m able to.


Custom SNES PC Boards – 27C322 and SNES Mask ROM

These are custom PC boards I designed that you can use to make your own SNES games with. Just check out the tutorial on how to properly populate it! Or, you can even check out the in-depth explainer on how the boards actually work.

I offer these in various packages, either with 27C322 or SNES Mask ROM pinouts.

  • Board Only: Just the board!
  • With Parts (No Saving): Includes a SuperCIC and capacitors needed for games that don’t save.
  • With Parts (Saving): Includes a SuperCIC, capacitors, resistors, diodes, and battery for games that save.
  • Prototyping: Includes a SuperCIC, capacitors, resistors, diodes, battery, and a nice socket for swapping chips easily!

Here’s the Etsy link for the 27C322 variant, and here’s the link for the Mask ROM pinout variant.

Note the prototyping boards have a HASL finish (silver-colored plating) that wears away easier as you move it in and out of the SNES console. So I use these with some headers in them so I can try multiple games on a single chip without having to solder and desolder them each time. All other ones have ENIG finish (gold-colored plating) that are like the original SNES cartridges. They’ll hold up for a long time! I use these for my repros after I test out the EPROM on my prototype board.

More designs are on their way!

27C322 to SNES Mask ROM – $2

Available on eBay as well!

This is a very simple adapter board that lets you use the ever-popular 32 MBit 27C322 EPROMs on donor cartridges. This will save you a TON of time adding wires to your board. You will need to provide your own 74HCT257 multiplexers (two in total). Detailed information, including schematics, can be found here.

27C322/160 to TL866 Adapter Board – $4

Available on eBay as well!

This board allows you to program 27C322 and 27C160 EPROMs using your TL866 programmer. If you elect to just get the board, you’ll need five resistors (4x 1 kΩ to 100 kΩ, 1x 220 Ω or similar), a 3-pin DIP switch, a PNP transistor (2N3906 or similar), a DPDT switch, and male/female headers and pins. You’ll also be able to program 27C800 and 400, but I don’t use these in the tutorial. Detailed information, including schematics, can be found here.

TSOP Adapter (III) to TL866 Adapter Board – $4

This board allows you to program 29F032 or 29F033 EEPROMs that are placed on TSOP Adapter boards from buyICnow.com with your TL866. Headers aren’t included, but you can find a ton of them online for cheap. Detailed information, including schematics, can be found here.

27C160 to TL866 Adapter Board – $3 (or $7 assembled)

This board allows you to program 27C160 EPROMs using your TL866 programmer. You’ll need five resistors (1k or above), two DIP switches, and male/female headers and pins. Detailed information, including schematics, can be found here. I’m selling these a bit cheaper, since they’re an older model and have been replaced by the 322/160 combination adapter (but they still work just fine!)
