even so, it will probably take a VERY long time to run. I don't think that's a good idea... waiting 5-6 times for a tapeloading error on a full 48k program like WSHAS thats 30-45 minutes life time, waiting for a 5 ball tictac movie takes 24h rendering, for about 2 seconds zx cpu time. ONCE zx0 is m...

including "unwrapping" give some 16bit values and CLOSE with 0 or bigger then 65535 then it SHOULD give back the correct nummbers just a test like others :roll: 3 DEF FN b$(d)=VAL$ ((CHR$ 193+"d" AND d<=1)+(("FN b$(INT (d/2))+"+CHR$ 193+STR$ ((d/2)<>INT (d/2))) AND d>1)...

thinking out loud: elias-gamma (or elias-gamma-string) is a bitstring of ANY length and ANY amount off numbers since its unkown what length next number will have its max number is SET by a series of zero's that realy have to be counted that is the gamma point '1' from and including there you take TH...

so, you only have to set (hl),0 inc hl (hl),elias and virtualy you are done if you count that 2^b bit i did not test this one but i want to know if its use-able for an zx0 ON Z80 machine its stupid, i warn you and in the C the elias is "optimised " directly after use. its feels like b64, s...

So, there is NO elias-gamma NULL , took me some time to realise that one ... :D :P :shock: :mrgreen: :roll: :evil: :?: :!: now its 98,7 % or some but it should write the encoding correct in mem, which is actualy just a shift with 8 bytes inside 16 bytes, so why dont i do that? since i wanted to see ...

NO IT aint working, yet but its at least working a bit, i had one stupid error , forgot exx hl BUT my basic part has severall QUOTE signs and inside and Token will be written in txt, with bas2tap,zmakebas AND txt2emu, so i quited that for now but i have to make it visual in memory so i will try diff...

well i made a crash by overwriting BASIC, but how and why ??? ; use ; eliasg021 ; pasmo -d --tap --name eliasg021 eliasg021.asm eliasg021.tap eliasg021.symbol ; cat elias.tap eliasg021.tap > eliasgamma021.tap ; bas2tap -selias -a10 eliasMCloader.bas elias.tap ; 10 DEF FN b$(d)=VAL$ ((CHR$ 193+"...

Hi wanted to mention "Logic RAM Banks" although you probably solved to problem there are TWO ways off counting the memory banks while they are the same chip https://github.com/ZXSpectrumVault/rom-disassemblies/blob/master/Spectrum%20128K/Spectrum128_ROM0.asm it mentions the difference in a...

nah, it aint cheating when ZX can do it btw, i realized, if zcc is used its better to avoid those IX and IY.. startdef ld hl,(DEF_ADR) ; hl = actual RAM location in BASIC listing at position off the DEF FN ld de,(mode) ld bc,4 add hl,bc ; adres+4 = var f rrc (hl) rlca ld c,8 add hl,bc ; adres+4+8 = ...

Hi how big is the change that zx0 will compress at a z80 machine? zcc DOES compile zcc +zx -vn -zorg0x5f00 zx0.c optimize.c compress.c memory.c -ozx0 -DAMALLOC -lndos -create-app BUT zx0 uses ARG[] in main if zx0.c was written for a zx memory, will the other parts compres? # JUST THEORY PSEUDO CODE ...

A standard USB-floppy probably won’t do, as it doesn’t give low-level enough access to the disk (as far as I understand). afai understand and read an UBS drive is a 9sector per track device while it should be 10 per track. i am not sure since format is a software matter, but modern tech has it own ...

cool and disturbing
i realize i have to reconfigure my woot not only with real names, but with real chronos aswell
btw, does it come with lyrics?

they have to make a big difference in their approach that litteraly 2 second "delay" couild have been hidden instead off a total block if its introusion by a bot then the 2 sec might be enough to check some double domains perhaps and maybe a small algo that count up wait time instead of ju...

ok, sytems are smarter and smarter, but then still there has to be a clue about that result else there wont be a "next page"

Hi I installed subliemeditor and the 2 sets of highlite testing on a pure basic file it show the line number in BLUE but only up to 999 from 1000 and above they become orange like the INT values is it ment to be that all line numbers are blue then you have a small typo/bug some where i use linux min...

i that case can you have a LONGER RSULT PAGE ??? since else its a WASTE of exact that searchTIME you protect so much with 10 PAGES off results the results MUST be found and thus the search already SUCCEEDED !! but there is that anoying script that blocks the content off this ALREADY FOUND RESULT so ...
