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.

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...

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...

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...

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 ...

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...

Uh. I am pretty drained right now. Just a note for the performance: If your CPU has enough L1 instruction cache, it is likely that the most common paths of the inflated code fit, so it is fast. My older Core 2 CPU likely doesn't have that much cache, and I was hitting its limits. At least this is wh...

I did the merge along with performance measurements. It is in the commit message: https://github.com/Jubatian/uzebox/tree/uzem140-hacks However I am simply unable to create a pull request today, I am trying to load that page in GitHub since like half an hour without success. My net access is atrocio...

Eh, all this mystery, let's end it! https://github.com/Jubatian/uzebox/tree/mode74 It should work (I hope nothing fell apart when I copied the mode into the master branch kernel from my test-bed). I think by now it had sufficient testing so whatever remains should be fixable, so it may worth poking ...

This is messy. I found out that we indeed have no doorbell since some retards kept wrecking it for the few dollars worth of batteries, and the landlord got tired of replacing it long ago (not the first place with this problem). Looking at UPS's page I can't find anything on how they actually try to ...
