Re: Consulta de como copiar de SD a SRAM

Hi, the sd-card module in the apple2 core is a really good starting point. pm me if you don't have time to modify it. The easy way out with real fat32 access would be a modified sms core bootloader core as a base (or atari2600) to load the sram, then boot another core like Antonio suggested (if i un...

Re: Cores para Addon Jamma del ZX-Uno

Hi, if the SRAM contents survive core change you could always load a core there using a bootloader, then boot up the correct core (and maybe transfer required files to internal BRAMs in case the core can't be changed to run from SRAM only) ? ... duh that's only helping if the only difference is the...

Re: Coco 3/Dragon 32

Hi, not really related to the port but if looking for cross-development tools you might want to take a look at lwtools assembler (http://lwtools.projects.l-w.ca/) The extras even contain patches for gcc (linux binaries may be available on some repo, compiles on cygwin too) If an 'almost' c compiler ...

Re: ZX-Uno on Papilio DUO ?

Turns out the DUO is really close to V3/4 and the only changes required for the latest vga test builds are the user constraints file and clocking (32MHz clock instead of 50MHz) + some additional signals to SRAM. The only problem i have is my lcd (old LG1517) doesn't really like the vga scandoubler o...

Re: ZX-Uno on Papilio DUO ?

Thanks :) Already took a peek earlier at the svn but had missed the wiki pages completely :/ The speccy core looks pretty damn amazing already, can't wait what it looks like when you guys consider it "ready" :D I'll look into the code and will probably ask stupid questions over the next few weeks, d...

ZX-Uno on Papilio DUO ?

Has anyone attempted to get the project running on a Papilio DUO board ?
I'd be very much interested in trying but can't figure out where to start :)
