Errors on first prototype:
* 4MB/ROMOE swapped because of part-footprint link wasn't updated.
* 245s in the wrong direction (AB/BA), added an ALS04 inverter on direction pins to fix.
* Cut /ROMOEL to AND (wasn't going low ?), connected /ROMOE instead.
* Missing connections for LOAD, H and EVEN to the CPLD, added jumper wires to pins 48, 49 and 50 respectively.
* Zoom problems, will try adding the RC delay on EVEN.
Puzzled works, KOF95 seems to work with some bad colors (maybe bad palette ram), Metal Slug 2 resets at the title screen.
