Dreamcast battery change

General, Guides Comments Off

Dec 072010

My Dreamcast was not saving the time and date settings I was putting in which got a little annoying as its setup for dumping GD-ROMs and isnt normally connected to a display.
The battery change is very simple.
1. Remove any GD/CD ROM from the drive
2. Remove the modem/BBA
3. Remove the 4 screws, one at each corner. They are normal screws which makes a nice change.

The top should now lift off and you can now see the battery on the small PCB at the front where the controllers connect (its the blue thing on the picture below
4. Remove the small ribbon cable, it just pulls out
5. Unplug the small fan from the board
6. Remove the 4 screws holding the controller PCB down.
7. I had to remove the 2 screws holding the power supply down, lift the power supply board up which allows the front board to lift out also.

8. Desolder the old battery and clean up the 3 holes.
9. Fit a new battery. I used a rechargeable CR2032 with radial pins attached.

10. Put everything back together and fire it up. Easy

My new programmer arrived today.
This things does everything I could ever want including EPROM/EEPROM/Serial EEPROM/Flash/Nand Flash/NV RAM/PLD/MCU MPU/PROM. It also covers IC testing, RAM testing and some special devices that Ive never heard of such as clock synthesizers. It supports over 53000 devices and the software is updated every month.

Goodbye G540, hello again Dataman

I have been using an old Dataman S4 programmer for years now. It has been an incredible piece of equipment and has not let me down once. I have the MOD40 and MOD42 adapters so I can program the larger EPROM’s 8/16bit.

A while ago I needed to program a GAL, which the S4 does not support without another expensive adapter so I invested in a cheap Chinese programmer that claimed to support them all. It served its purpose of programming some GAL’s but has been used very little since as its just not that good.
More recently I wanted to program a PIC16 for the NAOMI DES Dumper and once again the S4 does not support this natively and the G540 did. I programmed the PIC with what looked like ease and off I went to test. The PIC displayed correct initially but any output from the security PIC was corrupt. It turns out that the G540 loads the EEPROM data as 16bit data therefore every other byte was 00 which rendered the program useless. I got around this by manually editing the EEPROM data with the G540 software just before I set it off programming and this worked but its not something I was happy with.
After a lot of thought and some pleading here and there with various people I have negotiated a very nice deal and Dataman are accepting my old S4 programmer as a trade in on a new Dataman 48pro2 programmer. This thing does it all and I look forward to its arrival.

CPS2 replacement game labels

General Comments Off

Nov 172010

Some time ago I found a collection of CPS2 labels for download. I ordered some sticky backed gloss paper and printed a few off to see what I could do as most of the labels on my games are in a poor state.
The non colour labels on the CPS2 games are usually blue on a white background where as the labels I downloaded were black/grey on a white background. In order to make these look a bit more authentic I ran them through Photoshop and changed the colour for something more suited.
I printed a couple of test subjects out on normal paper just to make certain the sizes were all correct which they were and set off my first print on the gloss paper. The result was very impressive but I had the blue too dark compared to the original. The first picture is the original on the game board, the second is the print out. I struggled with lighting on all these pictures so they arent too good.

The colour labels I have also came out very good.

The Dungeons & Dragons label was not in the collection of labels I had downloaded so I carefully removed the label that was on mine (it was hanging off anyway) and scanned it in at a high DPI. As the colours were a little washed out on the original I adjusted them a little in Photoshop. The results were much better than I could have hoped for.

Overall im very happy with the outcome of these labels.

If you need replacement labels contact Spectre over on the Arcade Otaku forums. The quality is superb.

CPS2 replacement serial number label

I finally got around to copying the serial number label from the front of a CPS2 board.
This is from the green unit, the others have the Capcom logo at the bottom instead of some crazy writing, I will get around to making that up too.
Its as accurate as im going to get it at this point without spending ages doing fine tuning.
