I have spent hours on various forums tryng to compile the various fixes (and their efficacy) offered against the laser burning issue on modded pstwo V12(and unmodded it seems). I have found: * diode fix * vandruden fix * summ0ne fix * slim fix (v1 to v4) * Neo-Fix Xii (from neoasic.com) * Neo-Fix Plus It appears that the problem occurs across all chips (Matrix, DMS, etc...) even so some claims that the Magic is less prone to it (hard to verify claim). The diode fix seems completely useless, the vandruden seems out of date. The summ0ne fix, even so a "passive" fix, is widely used by many modders but most of them cannot explain why they use it and not another one. I suspect because it is easy and cheap. The slimfix uses the matrix team concept using a pic to stop the CD/DVD controller during mechacon crashes. It would appear that this fix cannot protect against all mechacon crashes and that the summ0ne might be "statistically" more effective. The Neo-Fix seems to use a combination of the slim fix and the passive fixes. The plus version is their latest. On paper it looks like it is the most comprehensive one but I could not find a lot of people with it so it is impossible to verify. I could not find modders selling premods with the Neo-Fix. Bottom Line: I still do not know if it is worth modding a V12 Pstwo. Any more information/experience about the above-mentioned will be greatly appreciated.
