Andreas is still sending more stuff my way.
Today we have a dump from Gaplus. The PAL is located at 9C and was taken from an unprotected chip.

Andreas has sent me another PAL dump, this time from Bosconian.
The board isnt working but the PAL dump looks good so it down as assumed working and will need converted to a GAL if it to be used with one.

Many thanks to Andreas for continuing to send PAL dumps.

Andreas has dumped PAL DD1-6 from his Dig Dug pcb.
The PAL was unprotected and will need to be converted to a GAL (unless you have a blank PAL chip handy).

Thanks to Andreas once again

Silent Scope RTC data information

 General, Technical Info  Comments Off on Silent Scope RTC data information

Today I burned a new Timekeeper chip for someones Silent Scope and since I had my board out for testing I thought Id run a few tests of my own.
I know with SS2 there is a checksum in the RTC data. This is not the case with SS1. It just has 13 bytes of data not all of which gets checked.
Here is what I found:

The first 8 bytes must read: 47 51 38 33 30 00 00 00 (GQ830 )
If any of this is different then you will get the 11p error

The next 2 bytes are the year. Mine originally read 20 00
It is actually the year thats shown in game on the title screen etc and can be changed to whatever you want, like this

The last 3 bytes must read: 55 41 41 (UAA). If this is changed to anything else then its 11p error time again.

From what ive tried you can add any data after this and it will make no difference.
The same data is also used across all versions of Silent Scope 1.

I will take a look at the SS2 data sometime too.
