No. 'Splosion Man is an Xbox Live Arcade (XBLA) title — digitally distributed, tied to your Xbox Live account and console license. Modding (RGH/JTAG) does not grant access to paid digital content.
Piracy Warning: Downloading pre-hacked XBLA packages violates copyright, risks malware, and bricks modded consoles. Not worth it for a $10 game available natively on PC/modern Xbox.
