Nice.

It takes me 3 years to do a new video mode.

You are a coding machine.
I would rather say, desperate :D Trying to come up with something for a large game still working fine with that 4K RAM.

Re: New bootloader

I got some info from him, most importantly, he used Mac OS X to populate the card. Poking around some I found a few references to that this system supposedly puts a bunch of hidden files on the card, it could be that the bootloader picks these up. Does anyone here have a Mac to give it a try? Does t...

High resolution ROM/RAM tiles attribute mode

Yet another video mode, experimenting towards something which could back a large game on a plain (no SPI RAM) Uzebox. This is an 1 bit per pixel mode with attributes at 4.5 cycles / pixel, what sets it apart from the slightly higher resolution Mode 40/41/42 group are two important things: RAM tiles!...

Re: New bootloader

Actually, he put the true Uzebox specs in the description. Click-bait. He knew what he was doing. Plus, we don't need I.P. lawyers around wondering about some "NES Classic" system. Not the kind of publicity we need. Just gave him the benefit of doubt. This is his most clickbaity title, he doesn't a...

Re: USBtinyISP issue

Yeah, it's working now. The 1.5K resistors were dropping the voltage way too low. Replaced them with jumper wires. Wow, nice find! I forgot to mention as I wasn't even exactly aware of it: my programmer is actually a Pocket AVR Programmer , which is only based on USBTiny, possibly somewhat differen...

Re: New bootloader

Could they be FAT32 long filename entries? If I remember correctly long filenames were added by Microsoft as some hack by using a previously invalid file entry format/code in the directory file table alongside the 8.3 file entry. I checked the specs back then to make sure those wouldn't interfere, ...

Re: USBtinyISP issue

There's 2 sets of 6-pins through holes for the ISP connector on my board revision but they looked identically wired. I assume it's for the underside ISP cable connector for Uzebox in plastic cases. It looks fine to me on your board, I have the same arrangement (same v1.3.1 PCB, only in black), and ...

Re: New bootloader

Only issue is if an old game only supports MMCs and has no update but it should still be possible to flash the game using an SD card, set the bootloader to game instead of menu, launch the game (which would crash), swap for the MMC card, then hit reset, no? I don't think we have any such game in ex...

Re: USBtinyISP issue

It should definitely work, I have USBTinyISP myself, and had no problem programming the V1.3.1 revision of the board (neither E-Uzebox). It doesn't seem to be the problem here, but pay attention to whether it is an ATmega644 or an ATmega644 P to use the appropriate part identification (ATmega644A an...

Re: The quest to a portable Uzebox - update!

Wow, sweet! :) I will definitely also like the showoff value of the portable, that it is easy to just carry around, no more praying for a suitable television or the proper socket on it!
