Re: Sonic The Hedgehog 16-bit on Uzebox

Can you believe it's been over 4 years! Time sure flies... Anyway; Someone asked me how the Sonic project was going and I decided to start it up again -- this time without writing my own video mode and just making it with with all the wonderful stuff that exists already. I finally caved and just shr...

Doesn't that cause an issue?

Re: Uzebox PCB -- Sneak Preview!

How do they know if you use the non commercial version for commercial work? Do the output files have some data in them that tells the fab companies it can't be used for commercial batches? Or is this more of a guilt based licensing scheme. Seems like they need to expand their offerings slightly for ...

Re: Building my custom UZEBOX: Some newbie questions

Thanks for help lightfoot256. RGB format (15 kHz) is commonly supported by most TVs with SCART input in Europe (I think TVs in USA don't have this input, and I don't know if they have it or not in the rest of the world). To use RGB interface you just have to remove the AD725 chip and supporting cir...

Re: Building my custom UZEBOX: Some newbie questions

I'm only interested in RGB output, so I'll remove the AD725 chip, and I'll output the video using the Sega Genesis/Megadrive/Master System configuration (8 pin circular din connector with RGB signals and mono audio) Wow; didn't even realise this was possible; I'm guessing your using an original cab...

2bpp Video Mode Ideas

I've been thinking about doing a 2bpp mode with tiles and sprites but shrinking the video output into the centre of the screen rather than making it stretched. This might look a little strange having just a small picture in the middle of the TV but at least it'll be high resolution! :-D. Anyway; wha...

Re: Uzebox PCB -- Sneak Preview!

I was also thinking about something. What about not having to require an ISP programmer? I.e: Put the equivalent of the ISP programmer's circuit on the Uzebox PCB? That could be done quite easily with an USB mega using the STK500 protocol. Could be a cool option. Also, wondering If I should not rep...

Re: Emulator in flash using Alchemy; needs optimisation...

I was under the impression -O3 did this automatically -- guess not; I"ve worked with so many different compilers; quite amusing how different two binaries can be that came from the same source but ran through different compilers (gcc vs intel's for example); I tend to inline all my methods out of ha...

Re: Emulator in flash using Alchemy; needs optimisation...

That's quite interesting ;) . Do you think any of those changes could be used on the C version as well? It runs like a slideshow on my netbook. In preparation for working on sonic again I had fun getting the emulator to compile on OSX; seems the biggest hurdle is the way SDL has been designed to wo...

Re: Sonic The Hedgehog 16-bit on Uzebox

Just wanted to mention that I'm still thinking about this project and it's not officially dead :-D. Just getting held up with the video mode requirements and trying to plan it out before I spend time implementing it in avr assembler... still aiming for: 120x88 resolution 8x8 map and sprite tiles 16x...
