While it's technically possible to run Resident Evil 5 on a GBA emulator using APK and OBB files, it's essential to understand that Resident Evil 5 was not natively ported to the GBA console. The game's system requirements and console specifications far exceed the GBA's capabilities. As a result, you won't find an official or sanctioned version of Resident Evil 5 for the GBA.

The GBA console has a dedicated following, and several emulators are available for Android devices, allowing users to play GBA games on their smartphones and tablets. Some popular GBA emulators for Android include Visual Boy Advance-M (VBA-M), My OldBoy!, and GBA. These emulators can run GBA games, but they often require ROM (Read-Only Memory) files, which are digital copies of the games.

Running Resident Evil 5 on a GBA emulator on Android may be challenging due to the game's demanding system requirements and the limitations of GBA emulation. You may encounter performance issues, glitches, or compatibility problems.

Resident Evil 5, a survival horror game developed and published by Capcom, was initially released in 2009 for the PlayStation 3 and Xbox 360 consoles, as well as Microsoft Windows. The game's success led to the creation of various ports and adaptations for other platforms. However, the Game Boy Advance (GBA) console, which was popular in the early 2000s, was not an official release platform for Resident Evil 5.

In the case of downloading Resident Evil 5 for GBA on Android, you'll likely need to find an APK file for a GBA emulator and an OBB file or a ROM file for the game itself. However, please note that downloading copyrighted materials, such as games and emulator files, without proper authorization may infringe on intellectual property rights.
