Apple II Peasants Quest Update: Progress on the Heights

deater78 2024-10-16 | More progress on the Apple II version of Peasant's Quest. The cliff climb is hooked up, and you can talk to the first keeper. Almost to full dialog completion, but there's still a lot of the game missing (mostly the archery mini-game and a lot of animations)

Peasants Quest II for Apple II teaser

deater78 2024-09-13 | Peasant's Quest II was meant for IBM PC / CGA, but what if you ran it on Apple II instead?

Or maybe I was just too lazy to fire up Turbo Pascal and do it properly

Apple II Peasants Quest Sprite Test

deater78 2024-09-01 | Working on Apple II Peasant's Quest again. The original had prematurely optimized sprite code, so here I am working on having the peasant sprites with full 6 frames of animation, partial transparency, and being on fire, all while against a 6-color background. All very difficult on Apple II, especially as I am targetting a system with 64k of RAM.

Apple II Riven Update 3

deater78 2024-08-19 | Version 0.11 release. You can poke around a lot more of Temple Island now.
Still fits on fourteen 5.25" floppies.

Apple II Riven (1997) Intro

deater78 2024-07-13 | Decided the Apple II Riven demake needed the full intro sequence

This was a lot of rotocoping.

Apple II Riven Disk 40 and beyond

deater78 2024-06-25 | Previously we looked at how much Riven (1997) would fit on a 140k Apple II floppy disk, but it only seemed fitting to see how much would fit on 5 disks.

For more info and disk images see here: http://deater.net/weave/vmwprod/riven

Riven/Dni Counting, Demoscene Style

deater78 2024-06-19 | I needed some Apple II lo-res routines for printing Riven/D'ni base-5 numbers. Once I got it working, things got a bit out of hand...

Apple II Commander Keen1 Proof of Concept

deater78 2024-04-06 | Testing to see if Commander Keen 1 can run on an Apple II.
Recorded on an actual Apple IIe Platinum
Controls are a pain as Apple II can only send key-down events, making platforming on a keyboard really difficult.

Plasma Mask 1k intro for Apple II

deater78 2024-02-11 | 1k Intro for Apple II shown at Lovebyte 2024. Finished 2/7 in the 1k oldschool intro competition. The long pre-calculation at the beginning is genearting a 768 byte sine table using the Applesoft BASIC floating point routines.

Rainbow Squares 128 byte Intro for Apple II

deater78 2024-02-10 | 128 Byte Intro demo for Apple II, shown at Lovebyte 2024. Finished 10/19 in the 128 byte oldschool category. This is two frames from the middle of a (slow) sierpinski rotozoom. It looks surprisingly colorful considering this is Apple II hi-res which only has 6 colors.

Apple II 6-channel pt3 Mockingboard Music

deater78 2024-01-19 | Most old systems with AY sound cards only have 3-channels, but the Mockingboard for Apple II has dual chips for 6 channels. Vortextracker supports this, and I had a request to see if I could modify my pt3 player to handle it. So here's a proof of concept playing Dya's "Dance of the Dead".
Note this is on an emulator, it probably won't sound as good on real hardware as there's a low-pass filter that tends to remove a lot of the bass.

More info can be found on this page: http://www.deater.net/weave/vmwprod/pt3_lib

Apple II Bubble Universe Attempt

deater78 2024-01-03 | yuruyrau posted a neat algorithm for drawing a "bubble universe" effect, and for once it looked like it might be possible on a 1MHz 6502 Apple II

Spent a *lot* of time optimizing 8.8 fixed point math, making lookup tables, self-modifying code, inlining functions, and unrolling loops. Eventually got a semi-decent framerate with 24 nodes. Doesn't look anywhere near ascool as it does on a faster machine

2023 Apple II Christmas Demo

deater78 2023-12-24 | 2023 edition of my annual Christmas Demo tradition. Recorded on real Apple IIe with Mockingboard card.

by Desire, code by Deater, Music by mA2E

There's some vapor-lock / vblank detection/ non-typical mid-screen mode switches happening here.

Twister Effect in Applesoft Basic (280 chars)

deater78 2023-12-08 | This is the type of thing I used to post on the (sadly defunct) Apple II Basic twitter bot.
I took a nice Applesoft BASIC twister effect by Marc Golombeck, made it lo-res, and size-optimized the code to fit in 280 characters (238 bytes on disk). I also tried to speed it up, or at least as much as I could on a 1MHz 6502 running the slowest BASIC Microsoft could be bothered to write. It looks much better if you ramp up your accelerator card (or emulator)

Apple II dots effect attempt #1

deater78 2023-11-27 | Working on getting a full version of the "Second Reality" dots effect going for Apple II. The original FC code has 4 multiplies and two divides per dot which is a bit much for 6502. Here I'm playing back recorded dots instead. This is 128 dots at 7fps which really isn't enough, ideally 256 dots at 25fps is reasonable but that won't fit in RAM.

Second Reality for Apple II

deater78 2023-11-04 | Won 1st place oldschool demo at Demosplash 2023

capture on actual Apple IIe

I'm working on a "final" version with improved effects and better sound sync

Apple II Plasmacube Proof of Concept

deater78 2023-10-31 | ...

apple II fake voxel proof of concept

deater78 2023-10-18 | it's actually just zx02 compressed rotoscoped frames. each frame around 1k. maxing out the 24k ram budget

apple ii animation proof of concept

deater78 2023-10-04 | 4fps, 17k

for those curious, it's pre-rendered (as opposed to doing 3d modeling on the fly)

each frame is a series of rectangles. Originally I was rotoscoping by hand but that was tedious, so I wrote a program that tries to find optimal rectangle coverage (it works ok but results in files 10-20% bigger than when I do them by hand)

this example is 4 frames per second. It can actually do better than that but then of course I'd have to draw more frames

Apple II Hi-res Plasma Proof of Concept

deater78 2023-09-10 | This is based on the lo-res Plasmagoria code by French Touch

Horrible frame rate, it's really hard to do full screen updates in hi-res on the Apple II with any degree of speed

Apple II Plasmagoria Scene in 316 bytes

deater78 2023-09-08 | An attempt to size-code a scene from French Touch's Apple II Plasmagoria demo.
Got it down to 316 bytes. Calling into Applesoft FAC floating point routines to generate the tables which is why it has 45 seconds of pre-calc.

Apple II pretending its a DOS machine

deater78 2023-08-27 | this was more trouble than it was worth.

a few scenes from second reality on Apple II [obsolete]

deater78 2023-08-15 | Note: since making this video I actually made a full version of Apple II second reality which you can see here: youtube.com/watch?v=RNOqu4vcDto

I'm usually not a fan of 2nd reality remakes, but then I found an AY-3-8910 version of the soundtrack and well, one thing led to another...

really it's just a few scenes and part of a rotozoomer

deater78 2023-05-03 | Testing out some hi-res graphics routines on the Apple II. This is an animation based on one from the Homestar Runner Strong Bad E-mail #152 "ISP"

Fits in 8k. The sound is "electric duet" out the regular speaker, though in the end that didn't turn out so great
