Re: New bootloader

As written, I cannot reproduce the problem during download. All the cards failing do so at the game selector now.

Re: New bootloader

Unfortunately, I cannot reproduce the MMC speed problems. Now some cards work at both speeds without further measures, while some don't work at all. Should I be sad? Happy? :roll: (But all working cards are unhappy with ACMD41 and need CMD1 instead, still.) (I used this tutorial, by the way: http://...

Re: New bootloader

Which games?

It may be okay for smaller chunks, the failure is roughly after 32KB. Maybe there's some buffer underrun with those cards then.

Re: New bootloader

Janka: I tried out the MMC patched version, however for some reason it behaves really odd (at least in the emulator). It works, but really slow, at the moment I have no idea why (this happens even when I use the hex you provided). I wanted to add the patch to the master repo so it existed as an opt...

Re: New bootloader

My wild guess is those ._ files are the resource streams. FAT does not support multiple streams per file but MacOS wants to store some metadata along which each file so it creates that crap. I also found it in archives made on Macs.

Simply ignoring dotfiles should help. How do we do that in 3 byte?

Re: New bootloader

Maybe he could do an image of the first megabyte of the card with dd and upload it somewhere?

Code: Select all

$ diskutil umountDisk /dev/disk2
$ dd if=/dev/disk2 of=image.dd bs=1m count=1

I even have 256Mb cards here which are SDHCs, so would fail with the old bootloader or most of the games.
Well yes. Exactly what happened to me. Those MMCs I found had been a problem solver.

Re: USBtinyISP issue

The device id does not match. This looks like crosstalk. You should check the soldering, and if you had a scope at hand, the rising edges of the signals.

Re: New bootloader

I wonder if we could include both code snippets into the bootloader. All what we have to do for that is checking the result of CMD8. If it's "illegal command", the MMC part should follow, otherwise the SD part. But you wrote there are only a few bytes left. Maybe it's possible to squeeze the code at...

Re: NEW GAME ALERT: Würgertime v2.0

Yes, it is pretty much done. There's still work to do on Music — there's 3K ROM space left but I'm not good with sound nor music. Levels — the current level set is somewhat knit with a hot needle as we put it in German. It's complete, but we need people who test all levels (compile with START_AT_LEV...
