A new battery for the Sega CD BackUp RAM Cart

Now that I have an extra backup of my Mega CD save files on the Sega CD Ultra Backup RAM cart I can replace the battery of my the old CD BackUp RAM Cart without worrying about data loss.
It is possible to do an open heart surgery to prevent the memory from being erased and replace the battery while the Mega CD is turned on . I went for that procedure to avoid having to copy all files from one cart to another again.

WS Flash Masta and Neo Pocket FlashMasta / LinkMasta

Two days ago Flavor of flashmasta.com anounced the pre-presale of a new WonderSwan flash cart: The WS Flash Masta.
For all Bandai WonderSwan owners this is exiting news as the flash/development carts for this system are very rare and expensive (e.g. the official WonderWitch or the WonderMagic Color).

To give you an idea what we can expect I’ll show you some carts he has made for the Neo Geo Pocket Color:
First there was the Neo Pocket FlashMasta and the Neo Pocket LinkMasta. I’ve used the Blue Version of the LinkMasta since 2011 and bought a new red 3D printed case for it last year.

Sega Pico Flash Cart Tutorial

This has been figured out and posted by Team-Europe in 2012 (link, link via link). Unfortunately the original document has vanished from the WWW. I’ll try to recreate this tutorial here:

The original document suggested to use Sesame Street: Alphabet Avenue as donor cart and pointed out to use an „Assembled in Mexico“ cartridge. As you can see a regular US cartridge won’t do the trick.

Philips CDI 220 Mini MMC 60Hz Modification and TimeKeeper Replacement

Recently I found a CDI 220/00 with Mini MMC mainboard. It’s a heavy and bulky unit that contains lot of PCBs, wires, screws and metal parts. It’s one of the first consumer CD-i players, later models have all components on one single mainboard (Mono).

A fully playable translation of Rent a Hero has been released last month. Let’s transfer it to a Mega Drive cartridge using this tutorial.

Atari Jaguar Mouse Adapter

Although there are still a couple of unfinished projects lying around, at least I want to finish this adapter before the end of the year. This is a list of things needed:

Instead of D-Sub15 connector I used a gender changer (male-male), it fits nicely in the housing of the D-Sub9 connector.

Philips CD-i Player Null-Modem Cable for Data Backup and Restore

Before messing with the timekeeper chip or exchanging the battery it is very important to backup game saves you don’t want to lose from the NVRAM. With a null-modem cable hooked up to a PC there are two options to communicate with the CD-i player:

To build a cable we need a standard serial extension cable and a male 8-pin Mini-DIN connector. Remove the male D-Sub connector and keep it for later (we need it for the Atari Jaguar mouse adapter).
