Re: Weber's Rants (tutorials)

Just a few thoughts. Uzem (the emulator) should not be affected in any manner by the fragmentation of the host as the operating system's interface hides that from it. Through the interface it can only see files, and build up some "fake" SD card like structure around them to emulate a compl...

Re: Mode 74 development

Hi! Yes, it is correct in the manual: for 8 pixels wide 4bpp tiles the most you can get is 24 tiles width (196 pixels), which pretty much fill the screen. For text, you can use an 1bpp row mode with 6 pixels wide tiles, that can give you 32 tiles (for the same 196 pixels). Pixels are 7 Uzebox cycles...

Re: Evolution of the SD card API

You should probably look in Mode 74's code for this, which does pseudo random access SD streaming in its HSync wherever it can. It needs many considerations to work well, but the result is useful. The limitation obviously apart from that it can access only an arbitrary 2 - 512 bytes long (even lengh...

Re: Emulator - get latest release here.

But Jubatian has some sort of hacked version to do that. Perhaps that could make it in the official release. :?: It is nothing fancy, just this . The problem is that you can only use this in Linux unless in some manner you can bring a console alive in Windows (I have no Windows at all, so I really ...

I just hope that's not a screenshot from CunningFellow's newest secret entry. I think I am going to withdraw then! :D (Sorry, couldn't let that pass... It so resembles Tempest's look and feel!)

Re: Mode 74 development

Poking around in the kernel I have an idea for creating an optional (but enabled by default) kernel integration layer. This would mean mostly a front end for the sprite engine exposed through the kernel's interface, and also a default memory map, so you could have a "basic" Mode 74 accessi...

Re: New Game: Lode Runner!

Huh, this is a very nice and solid game! I remember it from the past, didn't play much it though (maybe I never even actually had it), so it is rather new for me. And I am stuck at the second level! I see how to solve it, even could grab all the gold, but I am just hopelessly sloppy at it :P When I ...

Re: uzemario custom levels?

Now I also have a problem. I wanted to play with it a bit, but for me the game doesn't run on the real hardware... I mean that I put it on an SD card, plug it in the Uzebox, and it just keeps resetting, unable to list the contents. I checked, it has this problem with mario.uze itself, even if it is ...

Re: Mode 74 development

I guess it is quite ready for doing some real damage :D At least there is definitely nothing more possible in the scanline loop... I think even CunningFellow wouldn't find a single cycle to use in there on its critical 4bpp path, maybe except if it was somehow hacked to use timer 0 termination, but ...

Re: Let's Unite, Broskies!!!!

Emulating the NES can not be done. Not enough RAM, not enough PPU... That emulator project basically only covered the 6502 with some NES specifics, and used sort of a stub for video generation, something very crude compared to any of the implemented Uzebox video modes. So for Uzebox, we have to do i...
