2022 - THEC64 Mini/MAXi/A500... Add UART/BACUP the NAND

Sort it out now.. Some of this was guess work cos the translator would show the wrong word or the sentence wouldn't make sense, so had to guess what he was trying to do cos some didn't make scene.. I can't do this with mine, I wish I could but the serial is it damaged so had to in the end put a Raspberry PI3 in with the c64 Mini so I can play CRT and that. Its a shame, I don't have the money to get another one, I am on ESA cos I am disabled. Anyway, just wanted you to know. . I don't speck German and the only language we had at school was English, in the 80s that all they had, in the 90s when my son went to school he so tort German in class.

Its cos of the Cloudflare error,I could only post half it cos the server didn't like it and thought I was puting a command.so it would come up with the Cloudflare error page,Proboards use Cloudflare server to host the boards. so the commands had to be changed,later on I will go thought it and put in a comment to remove the space before pressing return and entering the command.If I can remove a space I will but if I can't I put a comment.

Thats all I can do... Dam Cloudflare

Fair enough man, if cloudfare is the culprit on this occasion.

Still, I'm hoping my efforts on the wiki page will save you the effort of wrestling with cloudfare.

Perhaps I better share my train of thought on this.

I feel that the forums are a great way for us users in the community to get together and share our insights and understandings.

A lot of these thoughts evolve and mature across the lifetime of the thread, can span across multiple threads and even across multiple sources (e.g. forums+facebook).

So I see wikis as a way of documenting the cream of that knowledge. Having a single wiki page on a specific topic can help people get up to speed quicker than having to trace through multiple threads (though that approach still has merit too).

With the present wiki, I think the only point of contention people might have is that presently I'm the only editor of it.

And I'll agree, it'd be better to have a community-based wiki with multiple users editing.

I haven't gotten around to setting one up, but if I or anyone else gets around to it, I don't mind porting my present wiki content across.

Cool just added this so every one knows...

*This part of the guide has spaces in the code because if you post them how they should be than you get a error page come up saying" Sorry, you have been blocked You are unable to access thec64community.online" they are marked with a *

So please look at the Wika page so you see what the lines should look like here.. gurce.net/c64mini/how_to_mod_the_c64_mini_to_add_extra_games
Sorry about this its cloudflare server,where the ProBoards are hosted,Very weird.
I am gong to fix this soon,in the next day or 2.I have a idea how and I should of done it in the beginning but just thought of it..

but have a idea of how to fix it now,use a picture of the code instead.. I can use the wiki code and copy it with Snipping Tool on Windows... and post it in place of the code that has spaces, but you will not be able to pasted the code so I will keep the old code up so when you paste it, you can change it to how it looks in the photo..

Well, we don't know. So far everything I've changed has survived firmware updates except that the game definition files that I removed were added again. But in theory an update could do anything they feel that is needed. Also they don't need to take into account that you have done mods, so things could definitely go haywire. 

The guide looks pretty good now.  Let's hopt the upcoming release in the US brings some new people interested in hacking the C64Mini to the forum, the more the merrier.

Hi Folks,

New to the forum so a big hello.

I just bought a C64 Mini and updated the firmware to 1.1.4 and been playing with it without any issues. I then came across this thread and decided to add the UART header so I can update the inbuilt games however when I run the commands to gain root I always get the following error no matter what USB stick I use. I have tried 4 different sticks ranging from 512MB to 8GB all to no avail.

Now I am no Linux expert but the e2fsck /dev/sda return 8 look suspicious to me which then prevents the mount from working.

Any ideas if this is a USB issue or an issue introduced with the 1.1.4 firmware.

All USB sticks are formatted as FAT32.

Thanks,

John

Thanks for the reply,

I have checked and it is definitely using MBR and is formatted as FAT32. Tried several different utilities to format the stick.

Hi all,

I tried to connect my mini-c64 to PC but it doesn't "view" the c64... no COM port in device manager.

Maybe I need a driver ? I have windows 8.1

thanks in advance
Best regardsStefano

Oh? It shows up in Linux by default just plugging it in? I'll have to look, I have a Linux machine to attach it to.

Can you describe your setup in more detail? What UART to USB device do you use? From the picture it looks like you have used a standard USB cable, not a UART-USB converter?

Have you soldered those wires directly onto the mini?

Try plugging the usb into the pc usb port and not via that hub.
