Raiden PCB is playing backwards, my Q25 only rotates to the 90 degrees to the right, I cannot access the test menu by pressing test, nor is there any switches on the board to be found.
I know I don't post here often, but any help would be greatly apprecciated.
Raiden: How can I acces the test menu?
You might be stuck. I've had boards that will only rotate one direction, or not at all.
If that turns out to be the case, the monitor's image itself can be rotated or fitted with a rotate switch to do so-- the four wires leading from the back of the deflection yoke (I think it's called)- the coiled up junk at the back of the tube- usually colored wires- connect to the chasis with a big plug, usually. Those wires tell the tube which corner to start the image in and what direction to draw in. If you turn the plug around, it will draw the image in diferent ways- normal, flipped, and mirror images of both.
You have to be carefull, though, to keep the two coordinates seperate as it will break the monitor if you do this incorrectly. I think that the plug of four wires must be devided into the two left and the two right and then each of those swapped or alternated. Sometimes the plug is already like that, and sometimes it needs to be cut in two.
Any one else have a comment or info on this? Search the forum- I think I've seen posts on this.

Before doing that, check your monitor chassis for a "reverse" plug on the PCB (some have this), which is another plug for the yoke wires. This will flip the image the other way around without having to cut the yoke plug in half.dpful wrote:You might be stuck. I've had boards that will only rotate one direction, or not at all.

if you look over your board there should be two small sets of 8 tiny white switches http://image.ec21.com/co/d/dipswitch/im ... 468398.jpg. If your raiden board has a small daughter board in the corner the dipswitch units will likely be blue with a silver/gray label and white switches. if it has a larger daughterboard underneath then they will probably be black.
they will be labeled SWA and SWB or DIPA and DIPB, switch 8 on DIPA/SWA needs to be set to on for the screen flip.
another useful one is switch 8 on DIPB/SWB which disables the attract sound. Set all other switches to off for arcade defaults, also you wont see changes until you turn the game off and back on.
hope that helps, you probably have figured it out already though

An orginal Raiden PCB has many Roms with imprints starting with SEI followed by numbers. it looks like this: http://www.mameworld.net/maws/img/pcb/raiden.png
I haven't played this game very long yet, so I don't know if the original has slowdowns. But if it is a bootleg it is very possible, since they were often made with cheaper parts. And no, slowdowns can't be fixed.

Hm i can't find SEI imprints, but then again it's dark in my cab's stomach.
I could see that there are EPROMS from Sony and NEC used.
Well but if there's nothing that can be done about slowdowns, nevermind the difference between a broken original or a bad working bootleg.
Well let's see if i can get a decent score with it

Everything is well now thanks for the links!
You learn something new everyday and this is one for the arcade PCB hobby. ^_~
I had the same problem with my American Technos Blockout arcade puzzler PCB when I first got it -- took me a long time to find the damn dip switch banks...and there are two seperate ones btw.
