27c801 are about three times the price of other common eproms. Of course they are cheaper in bulk, but if he wanted to buy the three to do one game it would be in the $20-25 range.

There are far better resources than eBay.  Regardless, he's doing games for what, $7 each?  How can you complain about that?

Now that I think of it I also burned eproms for an arcade hack I made.  But there's no such thing as arcade flash carts.

There isn't much need for them since you can buy MAME and FPGA based multi-carts and PCBs.

alright, i'll weigh in here, in COST, including label, donor, and eproms, SNES repros run from $15-30
thing is, there's a lot of extra work, trimming wires, rerouting, etc.
if you want to do it via TSOP, the cost is pretty much set at $20, with no rewiring, depending on how you do it.
thing is, that way is actually quite a bit more difficult, as TSOP chips are a pain.

so either way, it's a lot of work, but i'd tell ya to just go back and change something like SNES Super Scope 6 or madden 95 into the game, rather than messing with the SFC carts, that way if you screw up your first couple (chances are you will) then it won't be a big deal.

here's the basic way of doing a 4 eprom SNES repro:

If my programmer supported 29F032 I would have switched to that a while ago. I would rather solder one SMD
TSOP onto a DIP adapter than do the rat nest of wires for a 32Mbit cart.


There are some upfront costs to switch to TSOP. A adapter will be $75ish and you need to design a print your own
TSOP40 to SNES DIP 36 pcbs. Having proto pcbs made can be expensive if you only make 1 or 2 boards.
When I looked into it, it was about $175 each for a 12x16 snap away pcb.

Smeh.  It's an authentic capcom street fighter 2 turbo arcade pcb I got off of ebay for 45$ shipped.  Since I already had a cheap willem with the right adapter (I think the willem plus adapter was something stupidly cheap like 25-35$ shipped) I just bought the right eproms, burned, plugged in, and payed.
