Homebrew [Release] uae3DS (Amiga 500 Emulator for Nintendo 3DS)

[Badda]

This is a port of Chui's UAE4ALL Amiga 500 emulator (http://chui.dcemu.co.uk/uae4all.html) to Nintendo 3DS.

Many Amiga games are well playable - a compatibility list (incomplete) can be found using the link above. The emulator runs pretty well on both O3DS and N3DS, however the extra speed on N3DS makes it even more enjoyable.

Download here: https://github.com/badda71/uae3DS/releases

Installation:

• Create directory /3ds/uae3DS on your 3DS SD-card
• Put your kick.rom file in directory /3ds/uae3DS on your 3DS SD-card. It must be called kick.rom, be a kickstart 1.3 image, and be the 512KB overdumped version. The kickstart ROM is copyrighted material so don't ask me where to get it from. You might get lucky by asking big G for "uae kickstart rom" ...
• Copy any Amiga disk images that you might have (.adf, .adz) to a directory of your choice on your SD card
  
• Install CIA with FBI, run 3dsx from homebrew launcher (put 3dsx file in /3ds/uae3DS dir) or run 3ds from flash card.
• Apart from this, a DSP-dump is required for sound to work correctly in the CIA version.

v0.1

ToDos:

• full 400px width emulation
  
• nice to have (and hard to implement): attach an SD-card directory as Amiga hard drive

If anybody wants to help with these ToDos, you are welcome to help me with a pull request on github
Any other bugs can be reported here or on https://github.com/badda71/uae3DS/issues

Have fun!

however turning on L2 cache and 804MHz in Rosalina menu on N3DS makes it even more enjoyable.

This is the first homebrew I've heard of needing this... cant your app just enable the New speeds itself?

It sure could, but this is the alpha version, so you need to wait a bit until this is implemented If you don't like it, don't use it ...

 

[Rahkeesh]

Well just asking since it wasn't on the to-do list.

super, waiting for CIA Version

 

[ElectricJelly]

Thank you so much for your work! People around me are wondering why I just shrieked at my phone.

 

[Zense]

Wow this is amazing work! I know a lot of other people who will also be happy to hear about this

Perhaps it would help if you specified that the 1.3 rom is specifically needed? (amiga kick13)

Really? I actually tested with 1.3 only and wasn‘t aware that the other versions are not working. Did you check?

first one I tried was 3.1, and it didn't do anything

Thanks for finding out. I updated the OP and will check the other versions as well .,.

 

[ber71]

Thank you!!
I noticed that the second link in the first post points to the vice64 bug report page, instead of uae3ds

 

[ArugulaZ]

Thanks for putting in the effort. I'll definitely be looking forward to later versions of this emulator when new features are included.

 

[Psionic Roshambo]

Thank you!!!

Very grateful!!!!

Not sure when I will have time to play with it, but I will keep an eye on this thread in case it is updated before I get time.

Again thank you!!!

Thank You for your work. An Amiga emulator with a constantly available keyboard on the bottom screen would be a BOMB. This would make it probably the best Amiga emulator ever on a handheld. Even the custom controls/mapping keys to buttons would not matter that much.

I am not that tech savvy with UAE and all, but why bother with mounting a directory as hard drive since most UAEs just use HDF files as harddrives? I thought it was some sort of a standard in UEA that this is the way harddrive emulation is done. Also isn’t it a bit overkill to add HDD emulation to A500? I believe mostly A1200 mode would benefit the most from that.

 

[Rahkeesh]

Directory is more convenient to add stuff to outside of the program, plus you don't run into 4GB+ size issues with Fat32. A500 won't run WHDload very well but if you want to use it as an actual computer, the option is nice to have.

Moreso than keyboard even I think stylus pad -> mouse would be pretty good, opening up a ton of games that aren't so playable portably on other systems.

Absolutely fantastic release @Badda, the Amiga is perfectly suited to the 3DS thanks to the resolution and touchpad for mouse/key emulation. That alone would make it one of the best implementations on a handheld.

Really looking forward to further updates once I've tried this one out, appreciate it and best of luck in your endeavours.

Would something like this help for the keyboard screen or are you looking for something more stylized?

Wouldn't those bevome a bit too small on the touch screen?

 

[Rahkeesh]

Yeah the resolution is so low. You can't really do more than boxes with letters in them.

Don't suppose you can bring up the system keyboard while keeping the game running, that would be wild.

Thats why I linked different styles, the fancy arty one above and the basic layout on the bottom.
