(ah, cool! Oh, by the way, maybe your vast amount of knowledge could come in handy on some of the other technical/programming topics that can be found somewhere in this Development forum!)

Well, erm, I browsed through them and indeed, most of them seem to have been answered already.

Hey how are you cas?
I heard much about you, even back in the old days (Im from Geleen)
Im a newby, and started develloping Spacemanbow 2 about 1.5 years ago.
I was wondering how you programmed your games back then.

What assembler, what tools, cross assembling???
Did you work in a team, who designed grapx etc. (I heard Pat from DP even helped you out graphwise, thats cewl !!)

Anyway, it seems that people here in holland think you're a legend or sometin,

well to be honest, not much dutch people back then created really impressive games for the msx!!!
I saw a bit of coredump and blade lords, and another game you made....

Yes, looks really cool !!

Norakomi: Thanks for the kind words. Much information and team info can also be found at parallax.shape9.nl/ , especially in the programmer's diary.

But for a brief answer: for the first game (Vectron) I only used a hex editor, and no assembler. After that I used wbasm for a bit and later gen80. No cross assembling, as I only had my NMS 8250 and no other computer. We used DD-graph. Other tools were simply developed in-house (music/sfx editors, map editors, erm anything really)

Team: me & pat. We both did gfx & music, and I did whatever else was needed. And put in many hours :)

Ey Cas, by the way, any idea why your Parallax logo animation (from Blade Lords, e.g.) is messed up in openMSX? Tongue

As was already said earlier in this topic, nowadays there are a lot of crossdev tools that can make MSX development much easier or more efficient at least. openMSX (of which I'm one of the codevelopers) is meant to be one of these tools.

Dunnoh about the logo, it works on my real MSX, so you should ask the openMSX people! Ow, that's you then Wink
In reality, I have a hard time remembering how that was done. I mean, it was supposed to be nothing too special, just a simple trick. Hmmm. I forgot Sad

cool,

Hey, another question. Could you tell me a bit about the feeling you have this day (being here, typing these words, being nostalgic etc..)

Erm... well nostalgic sort of sums it up.

It was a nice time. New stuff has come along and I am also very glad I moved on, otherwise I would've felt stuck. Being here for now is nice, maybe shift some knowledge before I really forget it.

Eh yeah, the next question was: what does it do, that trick? Tongue Probably it's just very tightly timed, which means openMSX is a bit off timing, which we know already...

Hi Cas, nice to see you around here, really like thework you've been doing over the years.

2 questions:

1- What is the average speed of the CD scroll (FPS wise) and what was the size of the game area ?
2- Can you talk a bit about how enemies are managed (level of AI they have, etc...) and how they are managed (chained lists or ?). Any particular optimization trick you've been using?
