Release notes

PlayStation Vita users will be happy to learn that the issues with gpSP (Game Boy Advance emulator) are now resolved, and it should work as reliably as it did before 1.9.1 (and perhaps even better now thanks to increased performance). We hope you get a lot of mileage out of this core as a lot of work and effort went into it to really optimize the performance of this core over the past few months!

Text To Speech support is now enabled for the macOS Universal build. You can access this by going to Settings -> Accessibility and enabling ‘Accessibility Enable’.

Some nice changes under the hood that are more technical in nature: config file loading performance has been improved immeasurably which should help out with initial startup times of RetroArch, loading config files as well as loading shader presets. Core info file loading itself has also seen many performance improvements. We are aware that despite all this, loading all the assets in the more feature-rich menus like MaterialUI/XMB/Ozone can still take a long time on systems encumbered by slow disk I/O, but we have some special things in store for future versions that should increase asset loading performance significantly.

There is now multi soft-patching file support. We will explain this in more detail below.

Highlights

Multi soft-patching support

If an IPS/BPS/UPS patch is found, will replace the last character in the filename with a counter and loop until another patch is found (in any format).

Example matching filenames:

Contra (Japan).nes
Contra (Japan).ips # Applied first
Contra (Japan).ips1 # Applied second
Contra (Japan).ups2 # Applied third
…

Notice that if one filename breaks the loop, the following patches won’t be applied too. e.g.:

Contra (Japan).nes
Contra (Japan).ips # applied
Contra (Japan) (Translation).ips1 # Partial name match, not applied
Contra (Japan).ups3 # Not applied either
…

Enhanced ‘Load Content’ file browser search functionality

1.9.2 adds the same search filter functionality that currently exists for playlists to the file browser when selecting Load Content. This means:

For example:

In order to support file browser navigation, the search filter implementation had to be rewritten. Instead of having a single menu-driver-level search filter, independent search terms are now stored for each menu list. This is a far more robust solution, and means that filters can be enabled for other menus far more easily (and without any hacks). To demonstrate this, 1.9.2 also enables search filters when selecting shader presets/passes via the file browser (I will try to add this in more places as time permits):

Finally, 1.9.2 makes the following changes to existing search functionality:

In addition to all this, 1.9.2 also enables search filter support when using the file browser to select cheats and overlays.

Optional menu screensaver animations

At present, when using XMB/GLUI/Ozone, enabling the menu screensaver will cause the screen to be blanked when the screensaver timeout has elapsed. 1.9.2 adds three optional animations that may be displayed instead – these can be selected via the new Settings > User Interface > Menu Screensaver Animation entry; animation speed may be adjusted via Settings > User Interface > Menu Screensaver Animation Speed. The options are as follows:

OFF: Screen will be blanked

Snow:

Starfield:

Vortex:

These effects are rendered using font glyphs; the performance overheads of all the animations are therefore low. This should also give you some indication as to how we are planning to reduce file I/O overhead across the board when it comes to asset loading, but that is something that we will be unveiling for a future release!

When using GLUI/Ozone, the screensaver will be tinted (somewhat) according to the current menu colour theme (XMB uses a fixed screensaver colour, since it does not have a ‘proper’ colour theme implementation).

OpenDingux beta: Add 50Hz support

All devices running OpenDingux Beta have native support for both 60 Hz and 50 Hz display modes. 1.9.2 enables 50 Hz functionality in RetroArch. The refresh rate can be toggled between 60 Hz and 50 Hz via the Settings > Video > Output > Vertical Refresh Rate menu entry; the value can be saved on a per-core/content directory/game basis via regular config overrides.

This makes OpenDingux devices (running the Beta OS) pretty much the only affordable/easily available handhelds that can run both NTSC and PAL content smoothly. The VICE core in particular benefits enormously from this addition.

OpenDingux beta: Fix IPU scaling when running GB/GBC/GG/NGP-resolution content

Further testing of the OpenDingux Beta port has revealed several more resolutions which are mishandled by the IPU hardware scaler. 1.9.2 updates the resolution blacklists accordingly, fixing scaling for the following content:
