Everyone knows that the PSP Others data is the most incomplete... but the main reason for that is because it doesn't have high charting games.
The others data is more accurate for more recent titles, but also for higher selling titles.... the PSP is about the same age as the DS, but it rarely has titles charting in the top 50 or top 100 for more than a couple of weeks, and as the others charts are less comprehensive it gets missed out.
------
Based on age, popularity of software and a little bit from Sony and Nintendo's fiscal results I estimate that roughly the "total software" figures for the consoles should have these multipliers:
PSP: ~*6
DS and X360: ~*2
PS3 and Wii: ~*1.4
