Have you ever popped in a CD-based PS2 game and noticed how fast it spins compared to DVD-based PS2 games, PS1 games, movie DvDs, and music CDs? This seemingly confirms that the Copy Protection for Ps2 games - like that of PS1 games, is actually still intact and working, suggesting that the DMA, Mechacon, and possibly the Operating System of the PS2 is still being emulated, where it is probably piggy-backing off the PS3's Disc wobble hardware, given that like in a real PS2 it blindly verifies all ps2 games instead of verifying by listed titles as is the case with Original Xbox games on the Xbox 360. So I went on to test this idea, and to my fascination it did not show up with 'unsupported software' (which is also under the GAMES section of the XMB, supporting my coat of paint idea) on the XMB but instead as 'Data Disc' in the Video and Audio Sections of the XMB - the exact same way as what happens if you try a backup ps1 game or an actual data disc on the ps3.

Backwards compatible ps3#
That quick liquid-wobble sound that briefly occurs is likely the wobble-check of the console in action, given that it goes away once the disc has been verified or not.Īnyway, I wanted to see if the PS3 will come up with 'unsupported software' when you try backup PS2 game discs on it, where if the result differs from genuine Ps2 discs it would suggest that it displays 'unsupported software' in place of 'Playstation 2 Format disc' after the game disc has been verified as genuine suggesting it's the ps2-behaviour running as normal under a different coat of paint instead of the coat of paint that is 'playstation 2 format disc' on fat ps3s. I noticed that for any ps2 game disc, once inserted and the tray closed the PS3 would make that quick 'liquid-wobble' sound (it's the best I can describe it) that occurs in PS2 consoles for a brief period prior to recognising a disc to be a DVD, CD, Data Disc, PS2 game, or PS1 game to the menu. My experiment involved tests of the following: The other day, I was experimenting with my Cech-4000 (Super Slim) PS3 regarding it's incompatibility with PS2 games to see how it behaves when I actually pop in a PS2 game disc. You may be wondering why even bother? Why should I even be curious about this? Well I'll explain the reasoning behind this curiousity, which in turn may even nab your interest. It has me curious to see if this will result in the ps3 thinking itself to be backwards compatible, where it should in theory output "PlayStation 2 Format Disc" when a ps2 disc is inserted.įurthermore onto what the result might be, I am curious to see when you select 'start' through the XMB if it will boot into the ps2 logo - proceeding to a likely crash or black screen due to there being no emulated components to do their job.
Backwards compatible install#
I want to ask whether it is possible or not - through HFW, HEN or whatever, to access the repository nodes of the PS3's Lvl 1 Hypervisor where if so, then the file "sys.hw.config#0" determining (via a flag of 1 or 0) could be accessed and modified.Īnd if it is possible, is it possible to change that flag to 1 (which would therefore state to the XMB when it goes to check the flag that the PS3 is indeed backwards compatible), and install that altered config file onto the PS3 as part of Hybrid Firmware or as a Hybrid Firmware update?
