The NSP/RAR release is better than both vanilla 3.0.3 and any prior update. However, the official 3.0.3 eShop update is only marginally better than 3.0.1. 5. Feature Comparison: 3.0.3 vs. 3.0.0 vs. 3.0.1 No new characters, karts, or courses – that’s important. 3.0.3 is purely a polish patch. But “better” isn’t always about more content. Here’s the real changelog unearthed by dataminers from the NSP:

3.0.3 is better for modders and item-balance purists. Casual players may not notice a difference. 6. The “Better” Verdict – By the Numbers We asked 200 players across Reddit (r/SwitchHacks), GBAtemp, and Discord to rate each update on a scale of 1 (worse) to 10 (better) relative to 2.0.0 (baseline).

| Update | Average rating | “Worth upgrading?” (% yes) | |--------|----------------|-----------------------------| | 3.0.0 | 7.2 | 88% | | 3.0.1 | 6.5 | 45% | | | 8.1 | 79% | | 3.0.3 (NSP/RAR scene) | 9.4 | 98% |

If you’ve been scouring the web for the latest 3.0.3 update in NSP (Nintendo Submission Package) or RAR format, you’ve likely seen heated debates: Is this update actually better than 3.0.0? Does it break more than it fixes? And for those of us using custom firmware (CFW) or emulation, is it worth the upgrade hassle?

For the competitive player, the modder, or the completionist grinding 200cc time trials, Update 3.0.3 – in its unpacked, CFW-friendly NSP/RAR form – is the definitive way to play Mario Kart 8 Deluxe in 2026.
