After installing RetroArch on Android (both stable or nightly), the official app names in system app info are:

• RetroArch
• RetroArch (AArch64)
• RetroArch (32-bit)

apps.obtainium.imranr.dev App Naming Inconsistency

Current Behavior

https://github.com/ImranR98/apps.obtainium.imranr.dev/blob/main/data/apps/com.retroarch.json uses

• name "RetroArch (Universal)"
• Note: Description already says "This is the universal release (32-bit, and AARch64)"

Expected Behavior

Change the name to "RetroArch" for consistency with official app info names.
