You’re welcome.

@roslof @mitu

Thanks for exploring this one - I assumed that my RetroPie upgrade had overwritten my retroarch.cfg files. The advice here has fixed my missing shaders in my install (a 64-bit Raspberry Pi OS install).

Running and updating the setup script, navigating
P Manage packages
C Core
43 Retroarch
U Re-install (from source)
has fixed the problem for me.

@lolonois I am really sorry. I finally got back to playing with the Pi today. I was all set to try out your hard work here. I thought I should begin with an updated ScummVM release, so I did that first. Lo and behold, TLJ works! I was able to boot and play the prologue scene.

I definitely appreciate your help, though!

After my genius idea to delete all stuff in this discussion, which only cause trouble and chaos, I figured out to do another attempt and post again. This is version 2 of the little app. The gui and commandline are streamlined into one app. The commandline options are flexible now and it supports a configuration file. Unfortunately in GUI mode only one patch file at a time is supported (but I think this is not a real issue and is a limitation in GUI only). And it can create output folders too. Updated the first post with all relevant information.

It started out so simple.

I've also noticed a problem with blending while I was helping to troubleshoot recent issues with missing textures, but I wasn't certain that the blending issue was an existing problem or something new, as I rarely test N64 emulation.

Legacy blending is disabled for certain games - including Zelda - here: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/mupen64plus/mupen64plus.sh#L201

If you're familiar with editing files via SSH, you can edit /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh and try removing zelda from that blacklist to see if the problem is resolved. I'll take a look when I have some free time.

@hiulit maybe some curl trick can do this. But let's just put it in our ToDo list for now 😌

Yes, the method to make two-handed "tank" controls work on a single 8-way joystick does not require any cheats, just a clever set of controls mapped to what is sometimes called a "tankstick". The mapping makes use of <CODE_NOT> logic where you are actually excluding certain input combinations. MAME lets you setup mappings like this by using a double-tap of an input while in the GUI menu which changes it to a <NOT>, so if you do several inputs in rapid succession, before MAME accepts an entry, you can make some combinations that work in interesting ways.

Here's a mapping for a single 8-way joystick to control two tank sticks like Battlezone:

Game Control Mapped to Right/Up Up <not> Right or Left <not> Down Right/Down Down <not> Right or Right <not> Up <not> Down Left/Up Up <not> Left or Right <not> Down Left/Down Down <not> Left or Left <not> Up <not> Down

There is an odd situation for Keyboard controller users in lr-mame2003 that requires you to first set all retroarch inputs to NUL using a per-rom config file if you want to do this. You can read about it here.

I am grateful for your support.
