Uzebox ported to flash!

[lightfoot256]

Hi,

Not sure how active the forums are anymore and I'm so exited at the jump from 2 to 22 frames per second I couldn't help but post here too! The original thread is over at: viewtopic.php?f=9&t=851&p=6458#p6458 in the emulator forum but I figured maybe people don't read in there much?

Anyway; It's still just a proof of concept at the minute -- not even a work in progress!! -- but I'm so impressed with progress so far I just had to share...

Great stuff, Chris! I hope you can iron out the audio problems and maybe Uze can host it one day.

Good to see you're still around

Awesome! Sorry for not answering on the other thread...I would not have been of much help, I never had time to look at the emulator code! After that, porting the emulator to an Android App would be the cream of the crop!

First public demo:
http://labs.widgisoft.co.uk/flash/fluze ... zebox.html

Controls:
A = Button A?
B = Button B?
Directional Buttons
Enter = Start
Tab = Select

No sound yet;

Only runs at about 20-25fps at the minute on my old Core 2 duo macbook; might run a little faster on a windows box?

Thoughts? Comments?

Wow! Seeing is believing. It probably runs at about 15-20fps on my Win box with a 2.3Ghz core2 cpu. Perhaps I have an old Flash version, I'll try downloading the latest. Btw, can you control the aspect ratio in flash?

In any case, that's an amazing achievement. Keep it up!

Yep; I'm cheating a little already and using a screen buffer of only 720x224 (not 720x448) and just scaling it up; I've also broken the way video is handled and am outputting pixels to the buffer when the emulator writes to the video port; this makes the calls very fast but removes the gaps that are caused by the delays between each out instruction;

The plan is to time the delays in the emulator and then just stretch the image back up to the required size at a ratio based on the delays; this means the flash runtime is doing the image resizing which is a little bit quicker .

I've noticed already that not all the games work in this version of the emulator; I did comment out huge sections dealing with sound, the sd card and eeprom support so it could be that .

Hehe; yeah; Around the end of last year I got handed a huuuugge project at work that's basically sucked my entire life dry for the last 6 months; just starting to come out of it now so getting my feet wet again in my own work .

I also started using twitter a lot more and noticed the tweet from adafruit about the uzebox; after watching the video and seeing the sonic demo I posted ages ago I knew I had to finish it; Then I got sidetracked by this port . I was planning on doing an asset demo of the sonic game using flash first and then started thinking about writing it all in C and having a port for uzebox and flash using alchemy and then all of a sudden I was porting the uzebox emulator... the odd life of a developer huh .
