Don't include the brightness adjustment to the color formula. Apply the brightness adjustment with upper and lower checks 255 and 0, then feed the adjusted valued into the color formula. that will help bump up the threshold between light and dark and hopefully give you more color range for the...

Didn't want to come off as offensive. your game looks like it will be fun :) there was another reason it was never utilized back in the day, the memory requirements. most dazzler demos were designed to fit under 8KB

(interlace)overlay with the dazzler. it won't work like you think because the systems that have dazzlers are too slow. most are 2mhz to 4mhz machines and the overhead and switching are just far too slow. dogfight uses interlace as one of the only examples for the dazzler. it will switch from...

some options: Cromemco meant the cyclops to be used in 64x64 grey scale mode. In the mode you have 16 levels of grey in that B&W mode and you can easily convert color to grey scale with a even simpler weighted formula which instantly converts color to B&W making it very fast for your needs. no...

I forgot to mention you could slightly improve your Euclidean color distance formula dist = (0.3*(r-pr)^2)+(0.59*(g-pg)^2)+(0.11*(b-pb)^2) This adds a weighted bias for color perception. it is still a step below LAB color distance but can give a little more help. This combined with 15 colors...

it should be the same order: 18H dark red RGB 127,0,0 19H dark green RGB 0,127,0 1AH dark yellow RGB 127,127,0 1BH dark Blue RGB 0,0,127 1CH dark purple RGB 127,0,127 1DH dark Cyan RGB 0,127,127 1EH dark white RGB 127,127,127 1FH is black again. it is different then 10H i use it to mean a...

The code is a little incomplete. The color palette is not 8 colors it is 15. The light colors are defined in the C code above but there are dark versions of colors. Color 1 dark red RGB 127,0,0 Color 2 dark green RGB 0,127,0 Color 3 dark yellow RGB 127,127,0 Color 4 dark Blue...

what is the color conversion table for the dazzler you have setup? RGB breakdown.

power is one of them. http://www.z80.eu/power.html http://www.retroarchive.org/cpm/misc/misc.htm I think what also makes Cp/m kind of amazing is when you think about something for it chances are it already exists and somebody made it back in 1980 you just had no idea. many cp/m programs ended...

I can speak from a DOS86 user and a CPM80 user standpoint: I was introduced to MS-DOS and variants first. more recently CP/M and variants. From my perspective they are about the same. The command prompt and tools work the same. programming environment also pretty much the same. now when you...

freedos is for 86 machines correct?

Run mbasic under cp/m you can then add the bascom compiler and run compiled basic.

Just something i have noticed. with many of these original ICs being 50 years old many of them just fail doing nothing. the solvents used during manufacture can continue to react as they were not 100% cleaned so over time the chips just fail. besides accidently causing damage there could have...

go with the terminal syzygy wrote, the ESP 32 FABGL ANSI Terminal. it has 64 colors and graphics support better then the Geoff terminal, along with Sound emulation and supports full VT-100 along with emulation of more then 10 other terminals. it allows you for example to run some Osborne and...

yes sorry i contacted the author back in 2024 but never heard anything from the person.
