Re: Parity check live

It's actually not a code location problem, but a screen location problem ;) What happens is exactly this: loading a Hires screen while in Text mode... Everything gets scrambled, there's no escape! BTW loading a TEXT screen would also crush some of the display... From there I have several options: no...

Re: Parity check live

Discovered a problem: loading a Hires screen will scramble the results. Maybe I should have an option to avoid actually loading the file - just checking, but I want the utility to remain less than 256 bytes long, and I think there's only about 8 bytes left...

Re: Parity check live

Please welcome LOAD VADER !
:D

Tried to make the program a bit more user-friendly, and wrote a small instructions program.
Have fun (or not) with errors!

Re: TrackOric - android "something" for Oric

Amazing good idea!
And no extra hardware except the audio cable...
I love that!

Re: TapOric - android TAP player for Oric

Hello everyone, I'm glad to share some success with my last project dedicated to Oric: TapOric . Yes! I have a good feeling about this ;) Basically it's a TAP player, but it converts data to WAV-like-samples in real-time and sends it trough headset-output to Oric. Currently working are FAST mode, t...

Re: Parity check live

Well spotted, Sam 8) In France and Belgium! In French, saying (for instance) that your health "fait le yoyo" means it's going "up and down", so it could apply to the data quality on tape. Right now, I tend to prefer Load Vader (sorry ISS), compared to a re-loaded WTF? (which remains "wrong tape file...

Re: Parity check live

Ha ha thanks, kinda love Load Vader too... And ISS, very good memory ;) I had a bit of regret not having used "WTF?", but what refrained me from using it was the fact that it would give no good results in a search engine... Assuming someone would search for it ;) "I will always load you" makes me la...

Re: Parity check live

I'm still working on a decent version of the tool. Should be released in two versions: one loacted in #400, the other located in the alternate char definition zone => both being at each end of the RAM, one should be able to check/load any file. Now, I need your help on the name . It's curently calle...

Re: New tape loading speed - testers needed!

Oooooh :)
I thought you were working on saving at fast speed on real Oric, I was wrong :)

Re: New tape loading speed - testers needed!

Interesting ;) The thing is that, after the header is loaded, there are several operations done by the Oric: displaying the program names, and so on. This requires time, and IIRC when saving there are more than 3 stop-bits sent right after the end of the header (from memory, it's 4 or 6 stop bits, b...

Re: Convert a byte as hex string (to display on screen)

And change JSR $CCFB ;Routine ROM print Atmos RTS With jmp $ccfb to scratch a few more cycles :) In my little program, I am actually directly printing myself the bytes at the desired screen address. Managing it myself saved lots of cycles - especially when, trying to count the ROM routine cost, I h...

Re: Convert a byte as hex string (to display on screen)

Be careful when playing with the decimal mode: That can have surprising effect on an interrupt routine that can trigger between the calls to SED and CLD. Do you mean ideally the author should have disabled the interrupts first? (In my case, as I'm operating while a program is loading, there are no ...

Re: Convert a byte as hex string (to display on screen)

Nice!
If I'm counting right, the table solution (the latest one, being closer to the 1st routine posted) is two cycles faster ;)
For 32 bytes (I'm not counting the RTS) against 19 though. But it all depends on what has to be optimised, the speed gain has a cost :)

Convert a byte as hex string (to display on screen)

One thing I always thought would be boring to do in assembler, is having to convert a byte value to display it on screen. For instance, A contains the value #60. If you directly put it on screen, on the Oric you'll get the ASCII char for "(c)". But how to display "60" instead, which will require two...
