As the cabinet is not as big as a SNK one, the CP is smaller too (23 x 8 in).
. . .
Can anybody please help me to make it the right size?
Before we start, are you SURE about putting the NeoGeo logo where the joysticks go? Joystick's gotta move -- makes a pretty big hole in the logo. If the idea is to use them as dust washers, you should print them elsewhere or you'll expose bare CP when you push on the joystick and the washer moves.
When I opened the file and un-grouped it, the large black rectangle size is 22.151" x 8.310". When you switch units to pixels, it looks like it is about 90 pixels per inch.
I'm not that good at this, but here's one way that might work:
1. Open the file.
2. Press Control+A to select all.
3. Group all
4. Ensure newly grouped object is selected.
5. Set units on top bar to px (pixels)
6. Click on the padlock (close it) to "lock" the aspect ratio.
7. Click in the box to the right of the padlock and enter "2400" (8" x 300DPI)
8. Deselect the padlock, ungroup until the large black background rectangle is ungrouped from the other elements.
9. Resize and reposition the black background horizontally as desired.
10. Press Control+A to select all.
11. Group all.
12. Ensure newly grouped object is selected.
13. File - Document Properties - (+) Resize page to content . . . - Resize page to drawing or selection.
14. Save
15. Export to printer's required format.
16. Profit???
