Long time – no blog. People watching this site “closely” or inspecting youtube now and than will have noticed, that I was not vectrex lazy the last couple of weeks. But there was nothing really all that specific going on.…
In May last year I wrote a forum post on Proboard (interrupt-driven-wangle). I always wanted to write a little bit in more detail about it, but somehow never did. Probably because of Vectorblade. Wangle is a “game” by Graham Toal,…
I am starting to sell my collection. First bunch of items: Sales page!
Yesterday I got a message via Facebook, that Vectorblade looks “crooked”. The person – for easy reference let us call him CSR – has a recapped very well working Vectrex on which all other games work ok. Symptoms: Trying to…

A few words as an intro to my optimzations. As long as the game is running good and bug free, I do not really care much about how the source looks. I don’t care if it is half “C”, half…
Dungeon (continued) Moving around a dungeon. This really irritated me at first and I thought the program had a bug. I double checked with Paul Robsons C version (running on my Mac). After each door (or secret door) I got…
World map continued Extracting all “Map” symbols and putting valid Vectrex code around it – results in another very “easy” looking function:(the calculated scale is due to using a BLOWUP of 4 – and a slight adjustment 🙂 ) void…
