Dear mrdav,
I definitely prefer the postage option, because I find that the game works perfectly (i.e. you get the music as well) when the CDs are burned 1:1. Also, uploading over 500MB strikes me as rather tedious and time-consuming.
(I've tried the CD image option; the game can be played, but without the music - even when the audio tracks are burned as a separate session. With 1:1 burning this problem does not arise.)
No need to pay for postage, but please feel free to send me your postal address via e-mail.
Done.
I'd be grateful if an aspiring El Presidenté could confirm whether the CD image mounts properly.
