Re: Arduino based EPROM Programmer

If speed is an issue, then convert completely to direct port manipulation.

Dump all the digitalWrites and digitalReads.

Re: Nintendo "Gigaleak"

The stuff that I'd like to see is the complete Satellaview library.

Maybe there's an alien society or secret government spy agency that captured and preserved all of the broadcasts.

I only know of three existing dumpers:

* Naruko's Kazzo
* INL's retrodumper
* Kevtris's CopyNES and Bunnyboy's USB version of same.
sanni's Cart Reader will dump FC/NES carts with an adapter. The code has support for all licensed mappers and a couple unlicensed mappers (30 & 71).

Re: read rom from SD card on SNES

Maybe looking at the code from Arduino-based SNES Cart Reader will help you: https://forum.arduino.cc/index.php?topic=158974.0 MichlK's posts have the initial SNES reader code. The project has evolved into a multi-console reader by sanni. sanni's Github is here: https://github.com/sanni/cartreader

Re: Using SGB as a makeshift SNES flashcart

Looking at the SGB boards that I have readily available: ICD2-N boards have SYS-SGB-NT or SYS-SGB-1. ICD2-R (21) boards have SYS-SGB-2. ICD2-R (61) boards have SYS-SGB-NT or SYS-SGB-2. SYS-SGB-NT = v1.0 SYS-SGB-1 = v1.1 SYS-SGB-2 = v1.2 This isn't a comprehensive list. This is only based on my small...

Re: Using SGB as a makeshift SNES flashcart

I have a bunch of SGB boards. I have at least a couple of each chip type. An example of the markings for each type: ICD2-N 21 [Nintendo oriented to bottom of cart] Nintendo ICD2-N 9421KP205 D93115 ICD2-R 21 [Nintendo oriented to bottom of cart] Nintendo ICD2-R 9429KP214 D93218 ICD2-R 61 [Nintendo or...

Re: GB Bootleg 32-in-1 Cart

Good points. I didn't desolder the PEEL chip or do anything to the PCB. I also didn't bother to trace out all of the pins. I modified my cart reader code to dump the ROM. The dumped ROM will start in an emulator and show the menu which is in the upper addresses of the modified Alleyway ROM. Alleyway...

GB Bootleg 32-in-1 Cart

I picked up a GB Bootleg 32-in-1 cart in a lot. The cart lists 32 games but there's actually only 15 games on it. http://i67.tinypic.com/ego6x1.jpg http://i67.tinypic.com/ve99xi.jpg I finally got around to dumping the cart. It uses a modified ALLEYWAY ROM as the base. The cart writes to 0x1000 to sw...

Re: How to program a NINTENDO POWER Cartridge ?

Made a couple edits to the GB Memory News Ticker text. The Puyo Puyo/5in1 had a typo at the end of the 5th line and the 2in1 Harvest Moon text was incomplete. The Harvest Moon News Ticker text lists the top 5 rewrites for first half of 2000. Super Mario Brothers Deluxe, Legend of Zelda DX, Kirby's D...

Re: Dumping Satellaview mempacks

BETA firmware is enough to read the BS carts (non-SA-1) and Memory Paks. Enhanced Cart Adapter is only needed for SA-1, SPC7110, and Nintendo Power (SF Memory Cassette) carts. Dragonbox.de got their latest Retrode production run and they're now available in their store. EvilDragon1717 planned to loa...

Re: Dumping Satellaview mempacks

You can use any of the slotted BS carts except for the SA-1 carts (SD Gundam and Itoi No. 1). RPG Tsukuru, Ongaku Tsukuru, Sound Novel Tsukuru, Joushou Mahjong, Same Game, Derby Stallion 96, and BS-X will work. If you should have the SD Gundam Map & Data Pak, I was only able to dump it properly with...
