where to download bin bootloader and SDHC card support?
Re: where to download bin bootloader and SDHC card support?
Hi!
The bootloader along with instructions for installation can be found in this topic: Uzebox SD Gameloader V0.4.5 (read the first post, .hex files can be fetched from the bottom).
Currently there is no SDHC support, however in the future it might come (however it wouldn't support already existing games which require an SD card, so you should definitely try to find an SDSC card).

is it possible to connect flash memory W25Q64FVSSIG replasing SD card. And write to flash memory all games
Re: where to download bin bootloader and SDHC card support?
Why would you want to do that?
All code was written for SD card (SDSC with FAT16 filesystem), you would have to replace these to use the flash chip. It might be possible if you set up a FAT16 filesystem on the flash chip (or at least I think hacking the bootloader to use a flash chip instead of SD card would be easiest in this manner), but no matter what, it would require coding. It shouldn't be that impossible to get an SDSC card suitable for Uzebox.

find SD card for 2 Gb is too expensive for now, only batch 5 items (20$) on aliexpress and 4 weeks of waiting, in retail store for 20$ I can buy 32Gb SD card right now...
Re: where to download bin bootloader and SDHC card support?
for fat32 need more space for bootloader, it seems project need to upgrade to ATmega1284P-PU
Re: where to download bin bootloader and SDHC card support?
it is possible to delete from library working with directory and deleting, writing, renaming files
library size will be small
library size will be small

Taking a quick look in Aliexpress' memory card department I see some better options (you don't necessarily have to get a 2Gb card, even including Tempest you could fit everything for Uzebox on an 512Mb one, without Tempest, just about any size you can possibly find is enough). You should possibly look around on other sites available to you as well.
The ATMega1284PU is not an option for Uzebox since it can not be overclocked to 28MHz reliably (it was tested in the past without success).
The SD card library is not an option since in the bootloader and most games the SD card and FAT code takes less than 2k, in existing games, most often there are no 512 bytes available for buffering, and neither 64 bytes for the library's base demand. A bootloader has to fit in 4k! So it isn't something simple to solve at all (however I believe an SDHC supporting bootloader will be made before the end of this year).
