No More Heroes: Heroes' Paradise was released in Japan last week, allowing the site PS360 to set to work comparing the new HD version (in this case the Xbox 360 release), ported by Feelplus, to the Wii original. After the break, you can see the intro to both versions, presented in split-screen. We suggest watching them in full-screen, because you can't really compare resolutions or detail inside a tiny window. You can, however, see noticeable differences in texture detail, and especially shading -- the Xbox version has crazy high-contrast shadows on everything. You can also hear the new Japanese voice acting, which sounds totally silly.
The second video compares load times between the Xbox 360 version installed to the hard drive and the Wii's disc-based version. Surprisingly, in some cases, the Xbox game takes much longer to load! While that's not a huge deal-breaker, Siliconera reports that users are complaining on Amazon about freezing as well. It's hard to determine how widespread the issue is, because it's an Xbox 360 game released in Japan, and thus probably not in that many hands.
