Re: Could anyone help me acquiring an Uzebox?

OK, thanks, I sent PM! Hope I won't have to smash the piggy-bank though for even all the spare pennies :)

Re: Could anyone help me acquiring an Uzebox?

Thought about that, but right now I have nothing to blug a BT848 into! I only have a laptop, and a very crammed space... And if I bought a desktop instead, I still would have trouble with internet connectivity (I can at least pick up the laptop, and find signal in some corner if things really don't ...

Re: Get that emu faster

I don't think it should be done. For me, adding update_hardware_fast() everywhere only bumped up performance by 3 percents (see PGO results: 93MHz versus 96MHz), and only by profile guiding (otherwise results were abysmal). For you, by this comment from before: On my desktop, I did notice a slowdown...

Drawing with correct aspect ratio

I wonder what you use for creating graphics for Uzebox games. I mean how you ensure that you draw with the correct aspect ratio. For myself I just found an I think acceptable solution. Gimp alone didn't seem to work since it can't zoom with uneven aspect ratio. But I found a screen magnifier, actual...

Re: Get that emu faster

Checked, the software renderer is responsible for this slowdown (-w). It is worse than drawing directly into the window (which didn't have any really noticable performance impact).

I have no video card problems here, that was my parents' computer far away.

Re: Get that emu faster

I figured out what was wrong with that build. It can get 78MHz on normal clean build. There is something wrong with how the flag set is implemented which you use for measuring performance. If I reverted to the old method of removing SDL_RENDERER_PRESENTVSYNC manually and commenting out the "whi...

Re: Could anyone help me acquiring an Uzebox?

I discussed over the thing at work, and there were people who did likewise with online shopping there for the convenience. So it indeed will work out! Uze: How are you with Adafruit? Is that OK if you fetch the extra components (as in the complete kit with SNES controller and a 7" mini televisi...

Re: Get that emu faster

I tested your branch. I used Arkanoid since I did most of my previous benchmarks on it, so it was a good reference point. Something is severely wrong with your build on my system. My peak is 78MHz on Arkanoid, as described in my commit. However I get the following figures with your branch: - 55MHz w...

Re: Tempest is possible

I am stupid. Simply renaming "gcrt1.S" to "gcrt1.s" makes it compile and run fine at least as far as my skills permit to go. I am not very good in these types of games (reaching the fourth web is a rare luck with me). I read this topic mostly through, and indeed, this game is an ...

Re: Mode 74 development

I am now writing some support libraries, particularly sprites and related RAM tile management. Maybe I will do some art sooner or later, and using Gimp's header output feature it is quite easy to get just about anything generated, so I might cook up some more sensible looking demonstrations. I don't...
