3 years ago
Victoria, Australia

When streaming/recording a run you must be able to capture the window to show what emulator is being used.

BizHawk is able to display the status bar below the game window. That must be displayed.

DuckStation will has specific requirements below. You are able to run without showing the window.

You must also state what emulator is being used when submitting your run.

Accepted Emulators:

Accepted Emulator on Mac:

BizHawk Setup:

Games can only run under the cue format.

  • Config > Speed/Skip > Audio Throttle

If you're using the Octoshock core

  • PSX > Options
  • Select either mednafen mode option
  • Deinterlacing the image is allowed. Select Bob in the same window. To verify that you are running with Audio Throttle enabled you must hit the increase/decrease speed keys [plus/minus] it will display a message on screen.

DuckStation Dedicated Rules:

These settings can be displayed by enabling quick menu (Default: Escape Key).

You must show settings of the core settings before/after the run, you must match these settings.

Display -> Enhancements

Custom settings are allowed for anything that isn't mentioned such as internal resolution scale. We would allow enabling "Show Enhancement Settings" to simplify the user end side. However, some of the settings do not appear if they're enabled.

Quality of Life Settings:

Settings -> General

  • Enable: Render to Separate Window
  • Enable: Disable Window Resizing

Settings -> Display

  • Use whatever renderer you prefer (Recommended: Vulkan then OpenGL)
  • Aspect Ratio: Auto or 4:3

For the quick answer on "why did we drop ePSXe?"

That emulator for PC has not been updated in 4 years and despite being the "most accurate emulator"^ it relies on plugins compared to the other four options.

^Due to being closed source, it was able to get away with faking the scores on the PS1 Test Suite. Games that are tested to what ePSXe states it "passed" has outright failed.

For the quick answer on "why did we drop RetroArch?"

Besides the core that was chosen not actually being kept up to date to the upstream version (mednafen), the authors behind LibRetro have committed a lot of fowl play that it's not worth supporting outright an emulation development team who harass other developers and create false narrative why "they're in the right" (they're not).

Additional Note:

Even though this was focusing on Emulation on PC POPs on PS2 was brought up and I'll quickly go over that. POPs is acceptable for the first two titles as long as you mention you're using it and if you provide the IGT. It's outright banned for Tekken 3 for the time being due to the strong visual glitches, if that gets fixed I'll make an update about it.
