Soft Modding a Playstation 2 Slim: No Mod Chip Required
I recently did a write-up on how to softmod a PS Vita and a PlayStation TV. The PS Vita scene has blown up in 2018 and a flood of new mods and homebrew are out. What scene isn’t booming in 2018? The PlayStation 2 scene. While researching Vita homebrew, I came across a video from 2012 where someone demonstrated a soft mod for the PlayStation 2 slim. I didn’t know such a thing existed, but hey – I’ve got one of those. So I went down in to the basement, dug it out of a box, blew the dust off it, and got started. Before you read through this guide, let me save you some time. If you take a look at this and decide that it’s not for you, you can...

GTA 3 has been ported to the SEGA Dreamcast

Grand Theft Auto 3 was once in development for the SEGA Dreamcast, but was then released for the Sony PlayStation 2 console. A fan is now porting the game to the SEGA Dreamcast consoles modified with 32 MB of RAM.

GTA 3 has been ported to the SEGA Dreamcast
Grand Theft Auto 3 (GTA) was released for the Playstation 2 console in October 2001. The game from Rockstar Games was once in development for the last SEGA console, however that version never materialized because the production of the Dreamcast ended early that year in March. Fans are now developing a version of the game for the Dreamcast and the iconic open-world game can run on a SEGA console for the first time. After all, it was a game that was pioneering for later open-world titles and is one of the best-selling and highest-rated video games of all time. Most players will likely never experience the new Grand Theft Auto 3 port on ori...

Using a cheat cartridge modified to accommodate DIP-32 type integrated circuits thanks to a tulip orZIF socket , one can use a Playstation equipped with a parallel port and a serial port, running the Unirom software, connected to a computer running the Nops software, to flash memory modules of type AM29F0 or SST39SF0 in variants of 10, 20 or 40 (128 to 512KB).

Modifying a Master System cartridge for use with flash ROMs
I have a ToToTEK GG-PRO flash cartridge to run homebrew software on my Game Gear however I have never been able to get it to work on my current PC and it seems that it's hard to find a Master System equivalent these days. A contemporary alternative is the Master EverDrive and it is by all accounts an excellent piece of equipment however it is a very expensive product. I had, however, heard that certain Master System cartridges could be modified to accommodate a flash memory chip in place of their stock mask ROM. I do say certain cartridges as it's the ones with separate mapper chips that need to be used. One such cartridge is Afte...

Component detail
Introduction Here are the instructions to modify a SMS cartridge to accept a Am29F040 flash memory chip. I used a 4-megabit cartridge that had a 315-5235 paging chip, in this case Phantasy Star. This cartridge also has battery backed SRAM, which is an additional bonus. The 315-5235 supports paging in all three banks, making it compatible with virtually every SMS game. For more information on the 315-5235 and games which use it, take a look at this document at SMS Power: Sega 315-5208, 315-5235, and 315-5365 Master System Memory Paging Chips Instructions (www.smspower.org/dev/docs/SMSPagingChips.html) Instructions 1.

ASM Tutorial Written by Jay Table of contents Introduction CPU Register/Flags Addressing Modes Opcode Reference FAQ's 1) Introduction This is a tutorial on 65816 asm used in the snes, made easy for dumb people to understand (sorta). In case you are wondering, I don't program in this language, so it is possible that I will write something incorrectly in this tutorial. If so, you can e-mail me at tennj@yahoo.com, to complain about how I suck at tutorials. Learning asm language isn't easy. If you already know a high-level programming language, the process will be a lot more easier. If you already know a low-level programming ...

Anomie's SNES Timing Doc Revision: 1126 Date: 2007-04-21 15:07:05 -0400 (Sat, 21 Apr 2007) <anomie@users.sourceforge.net> This is a document intended to describe various aspects of SNES timing. It will probably not be useful unless you already know a good bit about the SNES. BTW, special credit to byuusan for the critical observation that the SNES returns to a known timing position on reset. Thus, a deterministic ROM (i.e. it doesn't depend on user input or any other randomness) will always give the same results on reset. And a series of ROMs which vary only in the master cycle count before testing some event (like the value...

SNES Layering Explained Piken (fdwr_at_hotmail.com) 2004-04-04 / 2003-01-20 http://oregonstate.edu/~robinsfr/snes.html http://members.tripod.com/FDwR/snes.html This doc assumes you already understand the basic concept of what a tilemap and scrollable planes are. The SNES can have up to 4 separate low-color backgrounds, 1 high-color scalable, rotatable background, and various combinations in between. How many backgrounds (bgs) and the color depth of each one is determined by the current video mode (0-7). The most common video mode used by the majority of games is mode 1, which has three bgs. They are num...

Anomie's SNES OpenBus & Wrapping Doc Revision: 1126 Date: 2007-04-21 15:07:05 -0400 (Sat, 21 Apr 2007) <anomie@users.sourceforge.net> Open Bus The theory is that the S-CPU chip has something called a "Memory Data Register" or MDR, which stores the value for every read/write. When you attempt to read from unmapped memory, no new value is supplied for this register and so you read the same old value over and over. Note that CPU IO cycles do not affect the MDR (and therefore the Open Bus value), even though the datasheet specifies addresses for those cycles. Note that JSL a pushes the old PB before reading the new PB, in ca...

TribalTap
The Tribal Tap is a multitap made by Naki. This company still exists or at least is related to Naki-World. There is a Tribal-Tap 5 which should be similar to a Hudson multitap (I do not own one to test), allowing four joypads to attach to one SNES controller port. Therefore with one joypad in the other controller port, this allows for five player play. There is also a Tribal Tap which allows five joypads to attach to one SNES controller port. It has a three position switch allowing selecting the mode: 2p, 5p, 6p.

Running Linux on the Sega Dreamcast
Introduction One of the more challenging aspects of learning about embedded Linux is the scarcity of cheap, compatible hardware. Sure, Linux runs fine on a personal computer, but does being able to run Linux on your workstation mean you can call yourself an embedded Linux guru? Hardly. You may not believe me now, but you will shortly. What's needed to really explore Linux as an embedded operating system is a well-documented, inexpensive and readily available hardware platform that isn't based on an Intel x86-compatible microprocessor. By excluding PCs, the list of candidates becomes: PDAs, internet appliances, and gaming consoles...
