After I had my first MVS at home, it didn’t take long until more arcade hardware followed. For example this CPS2. It looks shabby and needs some work, but it already has a Darksoft CPS2 Multi Kit installed.Continue reading Capcom CPS2 at Home
When I bought a second-hand Sega Pico in 2015, I immediatly noticed that something must be wrong with it. I didn’t expect a lot of interactivity or gameplay, but at least it should let me draw something. It turned out that the pen was registering the position/movement and also made a clicking noise when pressed down, but nothing else happened. The error was quickly found and repaired (broken micro switch), but the photos have been waiting on my hard drive ever since. A short repair instruction was posted on the ASSEMblergames board in the following year, so I didn’t see the need to rush out an article. Well, here we go:
The label of the pen is missing and it seems that somebody tried to open it up before me:Continue reading Sega Pico Pen Repair
Two more modifications for my Super SD System 3 v2, to bring it onto the same level as the new revision B.
First things first, there was also a new firmware released that fixes the reversed audio channels: 1.02 R05Continue reading Super SD System 3 FBX and FU-RGB Mods
This repair was not planned at all and took place while I was waiting for the capacitors for my CDI350 to arrive. I was thinking about buying a SX-1 or SX-32 extension for my Amiga CD³², and was recommended to go for a much cheaper modern extension: the TF328.
The TF328 needs a Kickstart 3.1 rev 40.60 to access the CF card, as there is no IDE driver in the earlier revision 40.56. Upon checking my CD³², there was not only the smell of electrolyte, there was also visible damage caused by leaking capacitors.Continue reading Amiga CD³² Recap and TF328
Last year I began to disassemble and repair one of my Philips CDI350 players. This has been covered in the article Philips CDI350 Repair Part 1.
After that, it took me a while to make a list of all capacitors, to find replacement parts (the original Philips part numbers are not useful anymore) and to find shops that had them on stock.
The scanned CDI350 service manual on ICDIA is missing the pages 78 and 79, which contain the parts lists of the servo and power sections. I found some of the missing parts in the CDI360 service manual and some by comparing the removed parts with both service manuals.
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.Continue reading Philips CDI350 Repair Part 1
What if your favourite CD-i game refuses to start or shows some weird behaviour? Most likely, this is to blame on a defective Timekeeper and/or laser. This topic has been covered years ago. There is another problem with the game The 7th Guest, which is completely unrelated to the problems mentioned above though.
Earth Command isn’t my favourite game. It makes 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.
Two quick fixes for my Super SD System 3 v2.
I inverted the orientation of the C60 tantalum electrolytic capacitor:
When I finally fixed my consolized MV1FZS last month and was able to play some games again, I noticed that it outputs mono sound only. It is now time to make 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.
Then it suddenly stopped working:
