beatmania / hiphopmania / beatstage region-locked/PCB repair? Help please!
Hi all - not too long ago I purchased a set of all the beatmania (Japanese) mixes and a JP beatmania cab, plus a beatstage (Korean) cab.
For reference:
So, I've been having some trouble with the boards, which are DJMain (Konami GX + Audio Extend: http://www.system16.com/hardware.php?id=826 )
First question:
Since I've been doing a LOT of swapping of the ICs for testing and I don't have any IC extractor that works with these, is Rom dumping possible for backup purposes? and would I be able to overwrite another "spare" IC chip in case one snaps?
Second:
The reason I've needed to swap them so many times is because I have 5 DJMain boards:
1x GQ753 (A3)
3x GQ753 (A4)
1x GQ753 (A5)
Some of the boards will work sometimes, for example I have a CompleteMix2 kit that works on one of the boards in the JP cab, but my TheFinal kit will not, on the same board. TheFinal works on another board in that machine, and another in the beatstage.
So, is there some kind of region lock for this hardware? And what exactly can I do to bypass this, if anything? Ideally I just want all my mixes to work on both machines, in any PCB. Are there any "universal" mods or boards that I could fix this with?
I should mention as well that some of the boards affect cabinet lights: sometimes they're all on, other board all off, other boards halfway, etc. Most of the boards I've tried in the beatstage cab have come up with a flashing pulse and loud popping noise when powered on.
Any help or insight would be greatly appreciated!
Thanks,
Paul
