Summary	04729: ncv1: [possible] First byte in gfx rom is wrong
Description	In "Namco Classic Collection Vol.1" is the first byte in the gfx1 rom (nc1cg0.10c) wrong. You can see this in the graphic, the number '0' has a red point on the right side (see animated gif). The byte is $04 instead of $00 like in the gfx1 rom (ncs1cg0.10e) of "Namco Classic Collection Vol.2". You can compare both roms from ncv1 and ncv2, the first bytes rom $1 - 2FFF are identical. I've heard from EEPROM-readers are doing it. If you set the byte to $00 the red point dissapear.

And one ebay auction posted an emulator screenshot instead, that made me a bit frustrated :P Then I googled the JP title and found some good photos.
