Finally finished MINI-GHOSTS, the #C64 #tape version of Ghosts of Blackwood Manor. Had to rewrite chunks of the game's logic to split it in 2 parts. Might remain exclusive to those who opted for the perk via the ZZAP Kickstarter and not be part of the upcoming public release.

Time for another bit of #retrogaming fun. I've always wanted to play Akalabeth - Lord British's start to the Ultima series. Well, using ร“scar Toledo G. port to GW #BASIC, I've been able to quickly convert to BBC BASIC for the #AgonLight. My beta version: github.com/sijnstra/Akalaโ€ฆ

I've improved the #AgonLight implementation of Daniel Martin's #TRSOS to make a more authentic #trs80 experience. Improving the display capabilities on #Agon was the goal. After many hours work (and help on the way), the results are great. Before & after. #RetroComputing
