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,…
31st of December – a new beginning!
I am starting to sell my collection. First bunch of items: Sales page!
26th of December 2020 – Intensity and Vectorblade V1.06, optimization WARNING!
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…

Optimizing is finished… with the exception of some odds and ends, that I did not explicitly mention. There is one last thing I want to share. The title screen! Following is the “original”: I converted that selfsame image using mighty…

The dungeon – Monsters Let us first look at the monsters in the dungeon. Some of them have a huge vector count. The demon e.g. uses more than 90 vectors. I said before, that I use a special routine “draw_synced_list()”.…

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…
Vectrex Aklabeth (1)
Over 4 years ago Pix started VecAkalabeth using the Vectrex32 BASIC cart. He finished the project and VecAkalabeth can be played… although the newest version was not made public yet – since the first versions of this will be part…
