ultimate_addon VS alu_cores

To build or modify the UCE, you’ll need this outdated tool that no longer builds UCE files properly

For posterity, I checked the original UCE from the COX v5 pack. It ran. So then I rebuilt it with the latest core from here using both the original AddOn Tool and the much better tool created by /u/meepowl. Both of those ran as well.

I'm pretty certain the Windows Addon tool uses a pre-built save image as there is one bundled with it and it doesn't include Cygwin ports of truncate, debugfs or mkfs which I needed to generate the save images. Our tool makes these on the fly just as the Linux script in the ultimate_addon tool does.

Hi. I'm trying to build a cross-platform tool to make building UCE images easier. The build scripts for Linux in the sauce_factory and ultimate_addon repos use mksquashfs which can be compiled for Windows but also use mkfs and debugfs to create the ext4 partition (as well as truncate and dd for various things but I can probably find a way round these).

I successfully built a UCE based on FBA libretro last night, using https://github.com/FalkensMaze1983/ultimate_addon and it worked but it sounds like you're saying this is not suitable if I want to be able to save any data. Is that right?

Download the AddOn Tool from here: https://github.com/FalkensMaze1983/ultimate_addon/tree/master/AddOn_tool

heres the download link for the addon tool https://github.com/FalkensMaze1983/ultimate_addon/tree/master/AddOn_tool, also read the readme so you know how to do everything below

A. Find a sauce from the same type of system. Use 7zip to extract the emulator core (.so) and the rom. Use AddOnTool (https://github.com/FalkensMaze1983/ultimate_addon/tree/master/AddOn_tool) to use your own rom or emulator core . Only mame roms are zipped. All others should be uncompressed.

For best results, I recommend this MAME2003+ core: https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20211108

The most robust core is MAME2003+. It's the one used for most of the games which come with the ALU and several users have built improved versions. I'd use this one from u/walknight : https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20211108

For posterity, I checked the original UCE from the COX v5 pack. It ran. So then I rebuilt it with the latest core from here using both the original AddOn Tool and the much better tool created by /u/meepowl. Both of those ran as well.

Pull the UCE that won't save from your drive, extract the contents to a folder, and rebuild the UCE from the contents. If the game is using a MAME2003+ core, replace the original .so file with this one: https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20210521.4

Take a look at this for proper syntax and config options: https://github.com/wn2000/alu_cores/blob/main/mame2003-plus.md

Could you post instructions on softreset? I tried burgertime , using cheat.dat from https://raw.githubusercontent.com/libretro/mame2003-libretro/master/metadata/cheat.dat and latest mame core from https://github.com/wn2000/alu_cores/

It's due to yet another incompatibility of the built-in retroplayer with the libretro cores. Try the latest mame2003-plus core here, where I've put in a workaround. FBAlpha/FBNeo may also work.

Here is a link to the core. https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20210521.4

Good question. Please take a look here: https://github.com/wn2000/alu_cores/wiki#when-building-a-uce-how-do-i-change-default-core-options

So, if you have One saUCE running which uses RetroArch, or just want to test your luck to see if latest retroplayer fixes the issue (I doubt it), you can grab the cores from here. I plan to put future builds, if any, on the same site.
