WARNING: You won't be able to re-flash once you've installed this BIOS, unless you use the EZ-Flash Recovery CD. You have been warned. Courtesy of Redbox/Dextrose and Naitachal.

GameShark PRO (Interact)

The Caetla 0.26 derivative from Hong Kong that allows you to boot imports/backups. Same software used in the various "Game Enhancer" carts!
E.M.S. 1.0
E.M.S. 1.3
E.M.S. 1.4
E.M.S. 1.4c (Chinese)
E.M.S. 1.5
The 1.5 version allows you to load imports/backups easier by stopping the cd motor automatically on boot up. You no longer have to go to the "CD-ROM" menu! Unfortunately, the hackers at E.M.S. messed up some of the memory calls and some PC Comms Link functions won't work properly (the MCUP & MCDOWN programs for instance). My fixed version, which xiaNiax have cleverly labeled version 1.55, can be downloaded here.
E.M.S. 1.55
E.M.S. GoldFinger 2.1
E.M.S. GoldFinger 2.2
E.M.S. GoldFinger 2.21

Zippy 0.33e (English) The best Enhancer BIOS I've seen! Based on Caetla 0.33 (all others originated with 0.26!) with switchable English/Chinese support, automatic motor swap (like EMS 1.5), and a nice boot logo. This is the one you should re-flash your cart(s) with. If anyone has further information on "Zippy," please email or post to the message board. Thanks to Rocket So for the original and RedboX for the English version.

Stealth: Universal Import Adaptor RedboX strikes again! Very nice European ROM for loading imports. Easy step-by-step instructions for newbies. NOTE: You'll need the "Ez-Flash Recovery CD" to re-flash your cart once this ROM is installed. The original cart did not have a CommsLink port. You have been warned. Also, it only runs in PAL mode.

E.M.S. 5.01 This is the same version used in the Game Enhancer 5.0! WARNING!!! This is a hex edited version of E.M.S. 1.4 , and IS NOT an official E.M.S. release. It was probably made by one of the "Game Enhancer" dealers to rip people off and sell more carts. Courtesy of Interesting Devices.

C.C.L. ModReplay 3.01 (Chinese)
CCL ModReplay 1.01 (Japanese) Similar to EMS 1.5, but displays a logo screen on power-up. As used in the PS-Z cart from Bung Japan.

Pro Action Replay 2M - 256k Hong Kong Pro Action Replay for 256k carts. Will boot imports and backups via swap in the "Play CD Music" menu.

Game Hunter 6.0 - LINK DOWN As included in some carts from Hong Kong. It's exactly the same as E.M.S. 1.5, but you all wanted it so here it is.

Games Blaster Pro 1.0 (NTSC fixed version) A 256k ROM BIOS that features automatic CD motor stop (like E.M.S. 1.5) for easy swapping when loading imports/backups. Will not work properly if flashed to a 128k cart.

OZ Game Enhancer 1.6 As used in the carts from Oz Chips.

PSX Vision Action Replay 2.0 - LINK DOWN As used in the carts from PSX Vision.

Action Replay 3.3 (Innovation) As used in the carts from Innovation. Nice logo!

It is possible to backup the ROM from your cart, or any area of the PlayStation memory, using only the ACTION.EXE program that is usually supplied with the PC Comms Link card. The method detail below will allow you to dump the ROM from any 128k cart to your PC.

In order to use this function, insert any game into your PSX and START GAME. Some carts require that you START GAME WITH CHEATS, even if you do not select any codes, in order for the PC to connect with the PSX).

Run ACTION.EXE from your PC, and ensure that it is configured properly with your Com port.

Select "3. Edit Memory" from the Action menu and wait for the PC Comms Link to connect.

Press F5 to perform a Memory Dump.

You must enter a filename to save to (c:\ps\bios.dat in the example), and the starting and ending addresses for the area of the PSX's memory you wish to dump.

The cart ROM (including codes) is located from memory address 1F000000 to 1F020000. This will only work with 128k carts! Newer PAR/GameShark (2.x) ROMs cannot be dumped using this method.

The main body of the PlayStation's memory is BFC00000 to BFC80000.

Select BEGIN DUMP to save the specified memory block to the PC.
