ofcourse..
Power Menu : Is a tool one can use as a disk menu program. It is full written in basic so anyone who knows msx basic can adapt it for it's own purpose.
The Mega Demo IV Promo : This is the promo disk we gave away on msx fairs one year prior to it's release.
Delta's Patch Disc : On this disk are patches/bug fixes for some of our programs.
Thunderbirds are Go Promo : This is the promo disk we gave away on msx fairs one year prior to it's release. Since we hadn't teamed with Qix yet, the music is still msx-audio.
Findit Promo : This is the promo disk we gave away on msx fairs one year prior to it's release. If I remember correctly it had 2 playable levels.
Findit - MSX2+/TURBOR Patch Discs : After the release of findit, we came up with the idea to make a msx 2+/turbo R version of the game with screen 12 pictures. As extra bonus for people who bought findit at the fair, over 2 months they could download these patches to upgrade findit msx 2 -> this version.
Konami Quiz 2 Promo : This is the promo disk we gave away on msx fairs one year prior to it's release. Since the devolpment got delayed due to new insights, the continues search for a composer and the artist who drew all the graphic to be digitized, it took another 5 year for the final game to be released.
Konami Quiz 2 Patch 1.1 : One year after the release of konami quiz 2, we released this patch to mostly fix grammer in both the dutch and english texts.
Konami Quiz 2 Celebration Patch : To celibrate Delta Softs 15th aniversary, we release the findit replayer. In this fashion, to celibrate our 20th aniversary, we gave away this celebration patch. It holds the 1.1 patch and added 30 extra characters to choose from.
Thunderbirds To The Rescue Promo : This is the promo disk we gave away on msx fairs one year prior to it's release. Of all our promos personally I think of this one as the best we made :)
All software above was made for MSX 2 or higher, with the exception of the Findit - MSX2+/TURBOR Patch Discs, this would upgrade the standard game to msx 2+/Turbo R due to the screen 12 pictures.
