Re: Issues with translated EPROM in Lagrange Point cart.

It may use the MMC5 Mask Rom pinout, which is different from the standard NES mask rom pinout.

Re: Glop Top Question

Age can make those epoxy blobs very brittle. I had a copy of Super Momotaro Densetu for PC Engine, and cannibalized the case to make a nice case for my TG16 Everdrive, so I thought I'd take off the protective plastic on the Hu-Card and take a look at the chips under it. The act of bending the hu-car...

Teensy 2.0++ As an EEPROM burner/reader?

As I understand it, you can make a pretty efficient EEPROM burner from a Teensy 2.0++ In fact, I just used one to program some NAND flash chips to downgrade a PS3 two days ago. Anyway, since my 3 PS3s are all downgraded now, I have no real use for the hardware anymore, but I just remembered that I h...

Mega Everdrive For Sale

I have a spare Mega Everdrive I've never really used, and I'm in need of some cash. I got it back in late 2013, made a cart shell for it, tested it, and let it sit on the shelf until now. So, I'm willing to part with it for $100 + shipping to anyone who wants it. The cart has no label, but I'll prin...

Selling items on NesDev forums?

Is this allowed?

I have a spare Everdrive MD, Modded Sega Saturn Model 1, and an S-Video modded Sega Genesis that I'm no longer using, and while I'd usually sell these things on ebay, I'd probably get dinged due to their crap policies.

Third-ing this.
If you're on the west coast in the US, I'll loan you a Teensy++2.0 and some jumper wires to do so.

Re: Markfrizb's new SNES pcb's, you need them now!!

If you can get 4 for $9 I'd love it if you shared these deals :) Go to Ebay, video games category, wholesale lots, sort by price & buy it now. There's usually someone doing a 3-4 "sports game" pack for $5 with $4 shipping. It's kinda random, but I got 2 of the 4 game packs and it had 2 lorom/ 36 pi...

Re: Markfrizb's new SNES pcb's, you need them now!!

Might be good for a dev board or test board, but I don't see these replacing sports games/Japanese horse racing games as donors.

First of all, I get a free shell for each game with the purchase of my crappy 4 for $9 deals from Ebay.

Re: 4 sale : Adapters [GB] (512ko & >512ko) / [SNES] GSU to

Would you be willing to share the gerber files for these? I was thinking this might be a good way to make an mother 3 cart with those crappy $3 bootleg GBA carts you can buy on Alibaba, if it was reworked to fit the GBA mask rom pinout (or the chinese pirate one, anyway). I know they use something s...

LP2950 Volt Reg & MX29L3211

I'm trying to do an SO44 repro, and I'm having some problems getting it to boot. Using an MX29L3211MC-10G, with an LP2950 as the voltage regulator, and I'm only getting a black screen. I lifted pins 1, 23, and 33 and soldered the output of the LP2950 to it, but no dice. I'm not sure on the EXACT mod...

Re: weird sram error on upgrade from 16kb to 64kb

I desoldered the chip and found the trace was lifted and hanging on by a bare bit of solder mask.
damn these fragile single-sided boards.

Tales of Phantasia on BJ3M?

Using a 2 mask rom BJ3M board as a donor: http://www.snescentral.com/pcbboards.php?chip=SHVC-BJ3M-20 I'm using two TSOP package adapters. P0 has 29F033C with the first 4MB of the ROM. P1 has 29F016B with the last 2MB of the ROM. I know this donor has A21 grounded. So, I'm supposed to wire Cart edge ...
