In my previous post on Doom for the Pocket PC I fixed the demo crash, bypassed the Serial Numbers Don't Match! check and moved the game onto the SD card. One thing that kept bugging me was that the fourth episode, Thy Flesh Consumed, was sitting in doom1.wad but couldn’t be selected even with cheats. I always suspected there was more to this port than what it shipped with, so I went back to it. This time I used AI (Claude) to help work through the disassembly of Doom.exe and cp.exe. It turns out the port does a lot more than it lets on. With a few patches it will play all four episodes of The Ultimate Doom, Doom II and both Final Doom games, Plutonia and TNT.

Most versions of the original Xbox can have it’s BIOS flashed (‘TSOP Flashing’) allowing for a custom bios to be used without the need of a hardware modchip. However, the last revision of the Xbox, known as 1.6, cannot have a custom bios flashed this way. Until recently it required a hardware modchip such as the AladdinXT. The user Prehistoricman at the Xbox-Scene forums discovered how to flash a 1.6 Xbox. This is a guide on how to flash the BIOS on Windows.

The HP Compaq T5500 is a thin client capable of running a variety of retro Windows operating systems. However, for storage it has a single 44 pin mini-IDE connector that has a small amount of flash storage connected to it. To be able to install Windows, a larger drive must be used. An extension must be used for a compact flash or SD card adapter to be able to fit.

For a while now I have had a second Game Gear that had no screen. It did have a GGTV installed so I was able to display the games on TV but I decided to install a new LCD screen. This worked well however I then noticed that the d-pad would rotate and get stuck. On closer inspection I could see why, the d-pad has a ‘lip’ around the edge that had broken off.
