Two portable Philips CD-i players (CDI350) came into my care last month. They show common errors, such as not loading any CDs and not storing any settings, and also flickering screens. Let’s have a look inside and repair them.
The screen becomes normal after a while so that I can navigate.
Earth Command isn’t my favourite game. It makes for some fun for a while, to tamper with the various settings and eventually watch the world burn, but it never got me hooked for a long time.
Then the reports of some people caught my attention. Some had trouble starting the game, as the screen just turned black after the intro, while others had no problems with the game at all. There was no common denominator to pin down the problem, as all the CD-i players they’ve used were of different revisions and generations.
The PSIO development cartridge, that I had preordered in June 2017, finally arrived this month. The whole package is very well made and looks almost like a genuine Sony PlayStation peripheral. The cartridge requires a modification before use, the PSIO switch board installation. The switch board detects the presence of the cartridge and switches the signals from the ODD to the parallel port.
This is an old rev. E1 SD2SNES cart, that I’ve bought several years ago from Krikzz.
SD2SNES did undergo some revision changes in the last couple of years. First there was Rev. F, that fixed some interference with 1CHIP units. Then there was Rev. G, that fed the DAC with +5V to improve the MSU-1 volume (and added some noise). And finally in Rev. H, the +5V change was reverted and an opamp added to fix the MSU-1 volume for good.

When I finally fixed my consolized MV1FZS last month and was able to play some games again, I notized that it outputs mono sound only. It is now time to make some some additional modifications to it.
MVS boards need both 5V and 12V voltages, and 12V is used for the audio amp only. As I’m going to add a new stereo audio circuit, there is no need for the 12V feed anymore. This consolized MVS draws the 12V from the now obsolete XL6009E1 DC-DC converter:
After having a great time with my MV2FS I was looking for something more compact that I could use in the living room. I came across a pre-consolized MV1FZS and played the entire Neo Geo library with it.
