Powerplay (Mega Games Pack) - Gordon Harwood
 

This page: http://hol.abime.net/6022 says the number of disks is 19, it's actually 20 Disks!

There are 16 games on 1 disk and 2 games on 2 disks, so that's 20 disks!

The HOL entry for Safari Guns is listed as 2 Disks and mentions the budget release is 1 disk, the game in this compilation is labelled 'Safari Games Disk 1' on the disk itself and when loading it the title screen says 'Safari Guns'.

Also, the HOL entry says this compilation was specially compiled by Gordon Harwood from the Big Box, Flight Command and The Power Pack compilations and the only game missing is Teenage Queen from the Big Box compilation.

UPDATE:

It seems there is version of Xenon 2 on 1 Disk in some releases of this as I've just obtained a boxed version and Xenon 2 is the 1 disk version with Speedlock and MFM tracks!

So HOL should list both 19 and 20 disks :)

Also, there is disk with both Krypton Egg & Eliminator on it but also has Eliminator on a separate disk too!
