Spectrum Computing

For drives, Gravitronic MK2 seems optimal. If you look closer, Heavy Duty adds only 20E of thrust but more than doubles the power requirement. I don't remember if there's a downside of using weaker drives with high level equipment, do you just move slower in that case or there's something else. Weap...

It's a good thing you've fixed the moving platforms, but in some ways they behave not as one would expect I think. For instance, it seems like the camera doesn't follow the hero if you move left or right while standing on one. Or e.g. with that hidden one at the beginning, it looks weird if you ride...

A TR-DOS monoloader program basically has this internal structure on the disk: Loader <B> CodeBlock1 <C> CodeBlock2 <C> ... And so on. All the blocks are located sequentially one after the other. Then you remove the directory entries for CodeBlock1, 2 etc, and add their length in SECTORS to the leng...

Moreso if it's presented for what it is.

I don't think Krakout is mentioned too often. Possibly the best Breakout type game on the platform. Not without a couple of critical flaws, sadly (the titular insta-kill ball turns the game into a RNG fest later on, I normally POKE the hell out of it before I begin), but otherwise the playability is...

feeling like real hardware because it is, FPGA is not emulation. https://memecentral.org/wp-content/uploads/2019/08/HAHAHHAH-LOL-meme.jpg Sorry, but no. A Spectrum is just a Spectrum, there's no way for it to be anything else. This thing, you can for instance use it to emulate a *gasp* C64 - it's j...

Not too impressed tbh. Disabling the beeper sound module was a mistake, the game has excellent beeper sfx with its own character and impact unlike the generic AY pew-pews. Little to no consideration on which theme is used where (what's that endlessly restarting LV1 song in the menu etc?). The music ...

Figured out the powerup at the beginning (hint: backtrack moar), and... yep, quite a few secrets in there it seems. I also can almost make it to the end of LV2!

Meanwhile, here's a quick TR-DOS version. Hope you don't mind.

Better still, do it as +3, +D and Beta for good measure! I've no idea how, but if this is requires a simple change to the LOAD_LEVEL routine and someone wants to help guide me through it if I get stuck then sure ;) I think it might just be possible to cram it all in a single 48K load somehow. At le...

Nice! This is easily game compo material. Great effort for a first game. Is it possible to fix hero movement on horizontally moving platforms? I don't know if it's hard to add in your scheme, but ideally it should be smth like 'if hero is on a moving platform, add platform_x_speed to hero_x_speed'. ...

Wrong. ZXDB always stores working download links for everything. Sites like SpectrumComputing can decide the links they will provide or not, based on their distribution policies, obtained permissions, etc. When a certain file is unavailable at a certain SpectrumComputing page, quite often this file...

[mention]Ralf[/mention], I get what you're saying but I can't agree with you. This community has grown an unhealthy tendency to exaggerate these things out of proportion because someone somewhere farted during the 00s. :) And there's the fact some things are simply mutually exclusive. For instance, ...

ZXDB preserves all original releases ZXDB is a database containing metadata information only. Exactly 100% of ZXDB content is stored somewhere else. Eh, not even gonna start with this mess. :? certain program pages show a list of playable files that cannot be downloaded <...> these files are curren...

I suppose my concern is that those games are lost due to very little documentation or storage of those games on reliable sites like this and it's currently very, very difficult to find them. But these guys don't even store all the original releases. What are you talking about? :lol: In fact, they'v...

I don't see how this could work. Could you share your code ?

Spectrum game compos be like

Sprites, definitely. The patterns for LD, OR/XOR and Masked are the same in about 99% cases, and instantly recognizable. Block fill: LD HL,ADDR LD DE,ADDR+1 LD BC,LEN-1 LD (HL),VAL LDIR MSB address conversions Screen<->Attr. R16+R8 arithmetics: LD A,L ADD C LD L,A ADC H SUB L LD H,A Wait for keypres...

And done. Post updated with the full archive.

TR-DOS is in second place - it does at least show the difference between BASIC, code and arrays, but not the start address and length of the Bytes: blocks, which is annoying. TR-DOS also has the LIST command, which is the more detailed equivalent of CAT, displaying that information among other thin...

And Chase H.Q. (also Ocean)

Thanks, and sure enough, we do use pattern lists here.

Re: source code, no problem. Once I consider it sufficiently finished, I'll release the proper package with documentation, a standalone XM converter and everything. Most of that is already done, so it shouldn't take too long.

At the moment, I've changed the pattern row format a little, and it seems quite effective. Even without compression, I was able to save about 2,5K of row data on "Na Zare". The new format is: +0: %nnnn dddd, - Note map, Drum (if present; codes 2~15). Note map is 4 bits saying if there's a ...

Awesome. This could be perfect for moderately animated menus and such. Cheers. Normally I'd prefer to leave the border alone when it comes to it... However, the inner loop of the original AMP was exactly 7T slower than necessary for this purpose, which meant one AND opcode was definitely out. :P Be...
