[GH-ISSUE #3342] [APP BUG]: Hi, I'm testing DRIVECLUB with ShadPS4 and running into softlocks caused by unimplemented stubbed functions. The game boots but gets stuck, likely due to missing controller initialization and PlayGo logic. #1026

Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

Here are the stubbed calls showing up in the log:

[Lib.Pad] pad.cpp:270 scePadOpenExt: (STUBBED) called
[Lib.PlayGo] playgo.cpp:94 scePlayGoGetInstallSpeed: called
[Lib.PlayGo] playgo.cpp:213 scePlayGoGetToDoList: called handle = 1 numberOfEntries = 100

Reproduction Steps

Problems:

scePadOpenExt being stubbed causes DRIVECLUB to not recognize any controller input, softlocking it.
The PlayGo calls (scePlayGoGetInstallSpeed, scePlayGoGetToDoList) seem to loop indefinitely, possibly making the game think it's still installing content.

Feature Request:

Could you please implement basic fake returns for the following functions?

scePadOpenExt: return a valid fake handle like 0x100
scePlayGoGetInstallSpeed: return a high value (e.g. 999999) to fake fast install
scePlayGoGetToDoList: return 0 entries to simulate a completed install

These changes don't need to be 100% accurate — just enough to let the game progress past early initialization.

System Specs (for context):

CPU: AMD Ryzen 7 5700X
GPU: NVIDIA RTX 2070 SUPER
RAM: 32GB

Few notes here:
Firstly, DRIVECLUB™ does get past early initialization on current shadPS4 main builds. If I remember correctly, you need to enable readbacks in the shadPS4 settings for it to work.
Secondly, scePlayGo functions are called by the game, when the game is loading content. There shouldn't be any issues with how these are implemented currently, otherwise no one would be running the game on official builds yet.
Lastly, our goal is accurate emulation. We're trying to avoid adding hacks, especially ones that would harm other game's compatibility.

Also, when submitting reports about game issues, please use the GAME BUG template and follow it's rules.
