Bung Enterprises made the Doctor V64 — Nintendo's $7M judgment dissolved the company
Bung made N64 copiers. Nintendo won a $7M+ US judgment. The company dissolved and reopened under a new name.
Bung Enterprises Ltd. · 2000-03
What happened
Bung Enterprises was a Hong Kong electronics company founded in 1994 that manufactured game backup devices — the Doctor V64 for Nintendo 64, the Game Doctor for SNES, and the GB Xchanger for Game Boy. These devices let users play games without the original cartridge, functioning as both development tools and game copiers. Nintendo pursued Bung through multiple jurisdictions — US lawsuits against retailers, CE-marking challenges in Europe, and a direct lawsuit in Hong Kong.
On December 23, 1999, a US federal court entered judgment in favor of Nintendo, awarding more than $7 million in damages plus interest and issuing a permanent injunction barring Bung from selling any device capable of copying Nintendo's works across the Americas. Rather than fighting the judgment or pivoting to a legal business model, Bung dissolved in March 2000 and immediately reformed as First Union Technology, selling the same products under the Mr. Flash brand. US Customs then seized those shipments, and the company stopped direct US sales.
Why it happened
- Bung's core product — game copiers that bypassed cartridge protection — was a direct infringement of Nintendo's copyrights and trademarks, giving Nintendo a strong legal case.
- Nintendo had the resources to pursue Bung across multiple jurisdictions simultaneously, while Bung was a small Hong Kong company with no realistic defense budget.
- Dissolving and reforming under a new name was a tactical evasion that worked temporarily but only escalated legal enforcement — US Customs began seizing the renamed shipments.
- Bung had no legitimate revenue stream to fall back on, making the $7M+ judgment a terminal blow to the original entity.
The lesson
A business built entirely on infringing someone else's IP is temporary arbitrage against enforcement lag — when the rights holder enforces, the judgment can exceed the entire valuation.
Aftermath
Bung dissolved in March 2000 and reformed as First Union Technology, selling rebranded devices (Mr. Flash, E64, Flash Linker). US Customs seized Mr. Flash shipments, and the company eventually stopped direct US sales. The Doctor V64 remained in use by hobbyists and developers for years afterward.
