Bad Apple (Amiga AnimPlayer- AMOS)
A downloadable comic
It is a Bad Apple - 68K Amiga port
Why? I was interested... Not a big deal but it was an 1 hour work in AMOS.
....but after another day of work ...I did some delta coding with the help of AMOS - Turbo Scene Extension ( like TOME) , also it redraws only the changeing areas.
-RAW version... a stock A500 +HDD can play the RAW version :)
-Encoded videos are smaller in size and the A500 purely plays it in 320x256, but hey it is AMOS and here is the Source code (encoder+AnimPlayer included).
Extensions used: AMCAF, TOME, TURBO2.15
Version -2020.07.13.-
-Faster version: Ntsc(30FPS) and PAL(25) simple buffered anim with replaceable low quality audio.

Hello, as a fan of Bad Apple running *everywhere* I thank you for this effort. Unfortunately I found that the RAW version, while working in A500 HDD, is too slow for A600 internal IDE because it lacks DMA.
On the other hand, I see that you have continued the development of Amos Anim Player on another dedicated page, and still produce Bad Apple examples there, but they're too slow for 68000 CPU.
So, I'd like to ask you, please consider creating a version sufficiently optimized / compressed / resized / whatever-it-takes :) to get the video (with proper vocals, not mod) running as good as possible on stock Amiga 600's internal IDE/CF. Thank you!
Hi,
For time to time there will be further updates on this project i am sure of it, but:
- further (delta) compression couses rapid (exponential) degradation in quality.
- using compressed data and decompress it in runtime also hard on the cpu.
- the IDE speed can't be faster by adding some magic code! :)
For the meantime you can try our "vector player" (https://electricblacksheep.itch.io/vectoranim-player).
it is much faster. it can stream ".iff" sound files from hdd wich is significantly less data than a full screen animation. The 2-color vector-anim & iff-music of Bad Apple will probably play faster.
Hey, thanks for the reply! I tried VectorPlayer but crashes immediately when launching, both 2-color and 16-color. Tested in fs-uae with settings equivalent to my A600 (2MB chip, 4MB fast, stock 68000, tried KS/WB 3.1 and 2.0.5).
I (kinda) understand the difficulty of implementing this, so no pressure, I was just trying to put the stock A600 on your radar, hehe. Cheers!
There is an other version uploaded "BadAppleFasteranim.zip". It should be more friendly with slower IDEs.
Thank you, the new version is almost perfect! You made it! :)
I only have to report that there is sometimes some audio pops and even repeated audio (circular buffer replaying I think). However, the image never slows down (that I can notice) and the audio never goes out of sync, even with the small errors I noted.
It is curious that the filesystem type makes a difference. My data partition is PFS3AIO and here the audio skips are quite noticeable. But in my system partition which is FFS it plays very well, with only the small errors I mentioned. The most critical section is around 58 seconds when the winged character is cut in half. Tested both in emulador (drive image, not virtual folder) and real hardware (A600+IDE with CF card), the symptoms are exactly the same.
As a mere test, I tried to convert the IFF from 11khz to 8khz (sounds awful but was just a test). Used audacity to resample and ft2-clone to convert wav to iff. Unfortunately the player didn't load with this iff, so I don't know if it would have made a difference.
So, as it stands, the faster version IS playable and enjoyable on A600 with FFS partition at least. If you can squeeze just a little more bandwidth, or maybe adjust the audio buffer, it would become perfect. I should note that the "normal"/RAW version has the opposite problem: audio is perfect, but with extremely lagged video.
TL;DR: Thank you again, you cracked it! I will showcase the fast version tomorrow on our monthly gathering of Associação Inércia in Portugal :)
Hi!
If You are a speed maniac... You can play the whole from Ram Disk.
Further size reduction in the PAL version, as the FPS has been reduced from 30 to 25. (now the anim is only 4MB)
Another tip is that if you have enough free fast ram (1,6MB, equal to the audio file), the player stream the audio from there and not from the HDD (a lot faster). The PAL audio is converted to 8khz. The audio is in principle handled in the standard format, but ...if you want to try, the conversion will definitely work with GoldWave.
From NTSC to PAL sum => 7MB to 5,6MB in size.
Enjoy.
I have the Amiga AMOS game maker's manual
, do you want it?
Hello!
Sorry, I just read it now (I somehow missed it). I have the online version. Thanks for the opportunity, but it will/would definitely be in better hands with a collector.
My Amiga days are long gone I'm afraid. I had a 500, 600 and 1200. I really enjoyed it. Poor old Amiga though. It was so capable as a computer. Especially graphic design. I have tried emulators, that's fun, maybe I will try AMOS again....
