You can also just INC/DEC Player_X

I'm waiting for another time window where I can continue work on my apocalypse engine.
I have 1-2 ideas to improve the part doing the particle/dot movement and next I want to add some sprites

But what you've got right now is great. If you want to do something else with it, that's your choice. I can only work on such fun stuff in short bursts, e.g. like during those two vacation weeks I just had. Now it'll rest again for a while, until another window opens where I can dedicate some time ...

Being a total noob in NES programming I have a hard time following your explanations, could you possibly post your code example?

Hehe... it'd be hard to beat the C64 in this discipline

I didn't find a video of the C64 version, but this is what I'm aiming at:

By significantly changing that approach I managed to almost double the speed of my particle engine (without any vblank extension!)

Now it updates 94 particles with 30Hz.

Thanks guys for all your feedback. I'll see what I can do with all the ideas I got now for the next revision of the engine

Ah, I thought I saw some of the pixels disappearing for small amounts of time...! =) I'm undecided yet if I'm going to do something against it or just allow it to happen ;) I think the MMC5 will let you access it's internal RAM from the CPU address space even while the screen renders, but that memo...

Well, I don't think it is too slow, in fact it is pretty cool. It is always faster than my pseudo-mode 7 demo that was computing a frame in arround 2-3 seconds or something like that (I didn't optimize my code). Thanks for the heads-up. I found the thread here and tried your demo, that's really imp...

Hi there! I'm currently working on a particle engine. I have a first draft ready, but unfortunately so far my efforts are way too slow. My goal was to move 128 Tile pixels at 60Hz, but my current best approach moves only 96 pixels at 15Hz :oops: Albeit my main VBLANK code is probably near perfect I ...

Hi there!

I'm just wondering if anyone knows of any tunes from SGNG that were possibly recreated on the NES by some fan?

Greetings,
Manuel

Hi there! Can anybody possibly help me finding this game? It is mentioned here: http://www.mayhem64.co.uk/sensible.htm I'd assume if it exists at all, then it must be hiding under some obscure japanese name. Here's some screenshots of the C64 version: http://www.lemon64.com/games/details.php?ID=2881...

I like lots of the Codemasters tunes, were all the European SID musicians make the NES produce very SIDish music

Try Matt Grays tunes for "Fantastic Adventures of Dizzy" for example. Partially it's getting as good as his Last Ninja score for the C64

To quote a Bard's Tale fanpage: http://bardstale.brotherhood.de/talefiles/index.html The NES version of The Bard's Tale was drasticly different from all other versions of the game. They even list it besides the regular series in the frameset. It has a different title screen, all different music, all...

Is there any significant difference between that and the other versions of Bard's Tale II? Judging by how significantly different The Bard's Tale is on the NES when comparing it to any other version, I'd think this would be true for the sequel as well, indeed :D Is there any translation team that's...
