These ROMS are from an original *NAMCO* board found at the back of an
arcade operators workshop. 

This board had the correct 'NAMCO' logo etched onto it.

The roms are *not* EPROMS but are true actual ROMs ( something of a rarity ).
Although the board was pretty ancient, it appeared to work quite well
considering. However, there was a *slight* sound fault so I put the ROMS onto
another ( similar )  board where they are working quite happily to this very
day.

There are a total of 5 PROMS

3 X game code ( 4K PROMS )

2 X graphics ( 2K PROMS )

This differs from other galaxian roms sets in that they are 2K eproms ( total
of 8 ).

Note also that many of the roms on the archives are modified original code.
Only one is correct ( 'normal' speed, only two escorts with the 'Midway' logo ).

You can be assured that the ROMS included here *are* the original program code.

* Change the path to the correct path for these roms in the .rat file !! *

These are the ROM images for Super Galaxians. These will work with
Dave Spicer's emulator and as ROMS for a logic board. The checksums are
as follows:

GALAXIAN.U 7DED
GALAXIAN.V F4F4
GALAXIAN.W E5AC
GALAXIAN.Y 331D
GALAXIAN.Z 1D1F

GALAXIAN.X does not exist

Use GALAXIAN.1H and 1K from original Galaxian roms.



[Jan/28/99]

Super Galaxians

These ROMs (SGAL.U, SGAL.V, SGAL.W, SGAL.Y, SGAL.Z)
were read in from a Midway Galaxian board. The stickers on
the EPROMs said "SG", so I assume they are a Super Galaxian variant.
The graphics ROMs at 1H and 1K were the original Galaxian with Midway logo
(GALMIDW.1J[sic], and GALMIDW.1K, which are also the same as SUPERG.1H,
and SUPERG.1K).
