S2000 - System Error - Game EPROM CRC Error -0xF001

[JDKMunch]

I'm trying to setup a vision game with ATA65 and SG285 -  when I put the 285 chips in the game gets stuck in a loop with the error Game EPROM CRC Error -0xF001.


I've tried several sets of 285 chips from different backups with the same error.   




The only reason for me trying the 285 game instead of the 85 game is to use a 6-6-3 led display.   If anyone knows if the 285 will work with a 6-6-3 I'll keep trying to figure out what's wrong -

Not going to be easy to figure out if you have bad backups or such

You have to interleave the 2 files correctly into a new file

You must know IGT's CRC routine and how to have HxD run it on the interleaved file.

If the 2 byte checksum at the end of file matches HxD calculated custom CRC then the files are good.

Most of my Visions have 248 or 380's. Don't know if they do 6-6-3

Would you be so kind and give me the checksum of your 248 chips -   


I need to know I have valid working chips.




Thanks

I don't know the checksum. Contact tollguy or erbs they will know.

248 does NOT support 6-6-3, 380 supports both.  However, 380 does not work with Wild Cherry Pie so it can not be used with that game.

Thanks -

Saves me from working on these 248 chips.

Now I have to find a 5 5 2 and a s**t
Adapter to make it with work with my button harness



Never ends I suppose

Good news   -   I finally got a working set of 248 chips - 


fixed my problems with the correct version chip


and I now have the game up and running with SG248 and ATA100065


And my 7 segment display WORKS!! <happy dance>


The only thing I'm pissed about is that SG085 would alternate reel sounds and have a reel stop sound
SG248 plays the same sound and reel stop is either solenoid or nothing.
