I'm seeing vertical brown stripes in most of the yellow stuff, and when the on-screen items 'flash' it looks like an extra pixel gets added to the left of things. Uhm, can you define "flash"? The only 'on screen items" that should be "flashing" are the four energizers.. and...

Second version is absolutely faster, almost too fast for arrow keys play! Is it possible to implement joystick support? Once again, great work :) Joystick support is on my to-do list for 1.3, I'm also playing with the idea of supporting the PPJOY type parallel adapters directly. That will top off s...

Were those twist-off or snap-off?

Ok, if you folks could run a check on the new version 1.2 for me that would be greatly appreciated. I've completely revamped how the sprite engine worked by implementing those back-buffers I mentioned. It now needs 70k of free DOS memory, but the performance difference is night and day... http://www...

This is cute - I started playing with the idea of a tandy/jr optimized version, cutting out all the auto-detection and other hardware support... and was going to rewrite it for 160x200... But that mode is scanline interlaced! That makes it slow as hell to actually implement code for! Not only does i...

The PCjr doesn't suffer from CGA snow, so a PCjr version should not be burdened with the need to check for the vertical retrace. The check isn't just for snow though -- because there are no hardware sprites you have to erase the element and redraw it (or at least that's the only reliable way to do ...

Well, we'll just have to try it out tonight on the real deal and see how it runs. Although if you are shooting for an 8Mhz AT with 16 bit video this might be painful. My original target was a 7mhz Tandy 1K, but the hardware just isn't up to the job of realtime sprites without flicker. Where is the ...

*** NOTE *** version 1.6 released After eight months in development and testing, version 1.6 of Paku Paku has been released. I've also revamped my programming website to host it officially -- so from now on if you're looking for information about Paku Paku, the new site is: http://www.deathshadow.c...

I'm just curious how many differences there actually are between the two -- if any. I've been working on a sound library that I'd like to work on both... I did luck into a nice .txt by one "John A. Ball" circa 1994 that FINALLY explained how it's actually mapped out which is how I've gotte...

Interesting, I always thought the purpose of READ vs. READLN was to not wait for the enter key -- quite unusual, but since it's likely just wrapping the BIOS calls who knows what the story is on that. Oh, if you want to bypass the BIOS function since the overhead of an interrupt call can be quite la...
