Requirements/Availability
Should only require the Vulkan renderer and a graphics card that is compatible with the Vulkan API. Will not work with either OpenGL or software rendering.
Android, Linux and Windows are all supported targets.
How to get it
The usual. Either you have Beetle PSX HW already installed, in which case you would just go to RetroArch’s Online Updater and select ‘Update Cores’. In case you don’t have it already installed, go to ‘Online Updater’, select ‘Core Updater’ or ‘Core Downloader’ (depends on the version of RetroArch you’re using), and then download Beetle PSX HW.
Explanation of core options
Two new core options have been added.
Dump Textures
While the game is running, it will dump all current active textures it comes across to a directory. The name of this folder is [gamename]-texture-replacements, and it will dumped inside the same dir that your content (ISO or other image format) comes from.
Replace Textures
It will attempt to use all HD textures from the ‘texture-replacements’ directory. The name of this folder is [gamename]-texture-replacements, and it will try to read this directory from the same dir that your content (ISO or other image format) comes from.
NOTE: Later on, we might add another option that allows you to point the dumping and injection path to somewhere else. Right now this is a problem for instance when you have your content stored on a slow disk device like a HDD but you want your texture replacement files to be read from your much faster but smaller SSD instead. Right now, you are forced to move the image to your SSD as well, because otherwise it just dumps and/or reads these texture replacement files from the same dir as the image, in this case the mechanical harddrive.
How to make it work
Make sure you have the textures extracted already in your [ganename]texture-replacements dir, and make sure that the dir is in the same dir that your game content file (ISO or other image format) comes from.
Start Beetle PSX HW, make sure that you are using the Vulkan renderer (it won’t work with either the software renderer or GL renderer), and then make sure the ‘Replace Textures’ option is enabled.
If it works properly, you’ll start seeing low-resolution textures replaced by higher-resolution ones.
