Nice to see some Homebrew News for the PS2, heres the info straight from Eurasia:

Homebrew replacements for RMMAN (and related modules) are now available in the PS2SDK. As the title says, the PS2SDK has received updates from me, which include a new copy of the RMMAN module from ROM v2.20. There were probably only two versions of RMMAN, with the latter one having minor bug fixes/differences that don't matter from the user's perspective:

* Does not clear the connected status, if a unrecognized response is returned within FindRemote().
* The in_buf and out_buf fields of the SIO2 data structure are set to NULL within InitFindRmCmd().

As with any RMMAN module, this homebrew version also requires a new SIO2MAN module. The freesio2 module from the PS2SDK was based on rom0:XSIO2MAN, which is only just newer than rom0:SIO2MAN. There also exists rom1:SIO2MAN, which is even newer than rom0:XSIO2MAN (and hence freesio2), which is used with RMMAN by the DVD player. Therefore, I have also created a variation of freesio2, known as rsio2man (where 'r' stands for Remote). This is just like freesio2, but has a slightly different export table (2 additional functions exported, different ordinal numbers and newer version).
