I have the BTTR version already. But it's not the same version as the one that used to be on Aminet and Edgar M Vigdal's site (the author released newer versions onto the net than the one BTTR possess).
And besides, Deluxe Galaga is still available to grab off Aminet, so it's not like the author sent a "please-remove-one's-games" request to them. Nevertheless, I have e-mailed the Aminet webmaster about the missing games and also e-mailed Mr Vigdal asking if he could help in any way to get his games back onto the net.
Pucman is a particular bugger as it means the D/L link from the WHDLoad site to the game is broken. Hence their slave can't be used for much else really.
