I have a PAL-A DOOM cartridge with the box and manual.

GOTHCLAWZ

How much is all this worth (excluding the controller)?

Blast Hardbody

$15-25 AUD, maybe a little less in that condition.

Nethergater

I remember buying this the day it came out! Probably in that condiiton worth about £5-6 I would say, not a particularly desirable game although I think the conversion is pretty good!
