Pretty printer / formatter for 6502 assembler code

Fri Nov 3, 2017 10:22 PM

Hi all.

I've wrote a pretty printer for 6502 assembler code because Aardvark was a mess of tabs and spaces, so I needed something to make it uniform.

I hope it's also useful for someone else.

REMEMBER: DON'T APPLY IT OVER YOUR ORIGINAL SOURCE CODE, MAKE A BACKUP FIRST!!! (it works for me but it could have hidden bugs)


Please share your impressions :)

Intellivision drawing sheet

Mon Oct 23, 2017 11:10 AM

Hi all.

I've made this drawing sheet for creating graphics for Intellivision, it's a squared grid paper for each pixel in the screen, and also a slightly thicker border for marking a 8x8 card, including row and column pixel counters at sides.

Print it at 100% ;)

Enjoy it!

The games that only run well in PC/XT

Wed Aug 16, 2017 11:25 AM


Just I was thinking in Digger (too fast in AT), Moonbugs and Styx (both using 160x100 CGA mode dependant on quirks) from Windmill Software.

Also remembered Buzzard Bait and Bushido, both speed up badly.

Not counting emulators of course, only anything that fails in 286 and over.

Any other game that you can remember?

Oregon Trail for Intellivision

Sat Aug 12, 2017 11:05 PM

Hi everyone.

I was reading there are no games starting with letter 'O', and I was increasingly worried so I started porting Oregon Trail.

Then I discovered indeed there are games starting with letter 'O', but already had coded the whole core of the game and I'm too tired for today to decide what to do with it.

Currently it's a text-only game, maybe I'll add later some graphic candy like in the first Apple II version like the map, the animals running and so :grin:

At this moment I'm not sure if the game is too difficult or there are bugs :dunce:

So I'm going to sleep and please enjoy this GIF. (click to animate)

P.S: As a tradition here, put your "I want two carts of this" message :rolling:

Bugs from Outer Space video

Sun Jul 23, 2017 9:23 PM



I've recorded a video of Bugs from Outer Space, I saw this game published originally in the 80-Micro magazine starting in March 1984.


As I learnt Z80 assembler language, I was able to port it and play in another computer but always wanted to see it like the original, in special because I never got the final magazine with the sound effects module.


Today I finally installed the SDLTRS emulator and recorded a video of the game, enjoy it!
