Diablocical?

@Nienn Heskil

I just read about a fixed AYFX player by Haplo: https://www.zxuno.com/forum/viewtopic.php?f=39&t=643
In your mFX code, is this fix incorporated?

Here you can find a nice introduction to using IM2: http://www.breakintoprogram.co.uk/hardw ... interrupts

As using the AY chip isn't as CPU-hungry as the beeper, I'm wondering if the 128k version plays faster.

There’s a couple of typos that need to be fixed in the loading instructions: tap —> tape, “symbol” in “symbol SHIFT” needs to be capitalized, and I’m not sure if the “R Type Loading Error” is a nod to Dave or also a typo. ;) P.S. I’d use straight quotes (shocker!) for the LOAD "" instruct...

Thank you for your continued efforts in creating all these maps, @pavero

Too bad, would make it more flexible to use for certain gfx. But I'll try to think of something else to compress them.
Thank you.

@Einar Saukas Is it somehow possible to use zx0 for data in a column x row square? I'd like to use it for gfx that I'd like to unpack to a certain screen location without touching the other gfx on the screen.

LnxSpectrum is also becoming a nice development environment with its assembler and debugger.

A few of my favourite AY tunes:

Aufwiedersehen Monty
Glider Rider
Platoon
Nemesis The Warlock

I see. I'm either turning off interrupts or use IM2. And as far as I see the ROM part IM1 calls is also just updating FRAMES on the interrupt. So I'm now doing that instead in my IM2 routine.

Sorry, I'm not quite understanding this.

Thank you, all.

I've implemented it. I'm updating FRAMES in IM2 and update my clock (Seconds/Minutes/Hours) every 50 count of FRAMES.

Machine Code, as opposed to BASIC.

Nice, thank you. On further inspection, when losing a life and its animation, that time doesn't seem to be counted.

Perhaps not a real issue for my purposes though.

Hello,

Are there any (MC) games where the (real) time played was shown? Not a countdown.

TIA

Edit: FYI I'm interested in studying how these clock mechanisms work in code and wonder if the FRAMES system var is always used, or if there are also methods with interrupts disabled.

Hello, I stumbled upon this page with games that contain border fx: https://www.speccy.pl/articles.php?article_id=61 It has screenshots to show the effects. I checked the ZXDB if these are marked as having the feature Border effects. The following aren't yet: Blade Warrior Chimera The Comet Game Gut...

I see... With both hl & de changed it now works - thank you

As I had crashes before, I placed the code to the screen just to make sure decompressed data was not somehow overwriting the code.

Einar Saukas By continuing with my issue, I hope I'm not uncomfortably interrupting the flow of interactions between you two. Thank you for the clarifications, Einar. I have followed them as follows: Given: The binary block is exported after compilation of code with SJAMSPlus with the instruction: ...

Einar Saukas In a new 128k game project, I am already using your zx0 de-compression for graphics in 128k banks to much satisfaction. But now, as it will be a physical tape game, to shorten the loading time I'd also like to compress the main-part. It occupies memory from 24832-65535=40703 which comp...

A typo, I presume?

@Andrew771

Glad to see you're still working on it. Can we access the latest version of ZX Like Pascal somewhere?

To save a block of memory in SpecEmu do File/Save binary file.
From the debugger you can also display blocks of memory.

With InkSpector you can also use SjasmPlus symbol files.

Great work, Tom
Looking forward to seeing progress.

Thank you for mentioning RetCon in the review - it's much appreciated! I've just posted a comment asking if you'd be willing to add a link to the event's Facebook page... A bit cheeky, I know, but the game is effectively an event exclusive in the UK. I had a chance to see the ULAPlus version for th...
