Aquaria not working (memory lacking) 6.39 pro-b10fix1

[GoogleCodeExporter]

When I launch Aquaria on my psp the game always return to XMB.

Tested with (all lcfw):
6.39 pro-10fix1 on psp 3000 "umd cache" enabled and disabled;
6.39 pro nightly, on psp go, "inferno & NP9660 iso cache" enabled (23MB) and 
"iso cache" disabled with "unlock memory in psp games" enabled.

Then I wrote an e-mail to Andrew Church. He told me:

"Your EBOOT.PBP runs fine on my PSP (PSP-2000 model). The symptom you describe 
sounds exactly like what would happen if only 32MB was available, which makes 
me think that your CFW version either isn't unlocking the RAM properly or 
splits it into multiple pieces (Aquaria requires that all the RAM be in a 
single contiguous block, as in 5.00 M33).

Did you build from the Aquaria source yourself? If so, you should have the 
aquaria.prx executable in your build directory. Try copying that to the install 
directory on your Memory Stick and running it directly from the PSPlink shell; 
it should output debug messages that tell you what's going wrong. If you see 
something like:

14.630597: src/sysdep-psp/memory.c:137(psp_mem_alloc_pools): Not enough memory! 
(want=02E00000 total_free=012A9E00 max_free=012A9E00)

that tells you your PSP doesn't have enough memory free. You can also
use PSPlink's "meminfo" command to check how much memory is available;
you should see something like:

        Memory Partitions:
        N | BASE | SIZE | TOTALFREE | MAXFREE | ATTR |
        ---|------------|----------|-----------|-----------|------|
        1 | 0x88000000 | 3145728 | 296192 | 268544 | 000C |
        2 | 0x08800000 | 54525952 | 54509568 | 54509568| 000F |
        3 | 0x88000000 | 3145728 | 296192 | 268544 | 000C |
        4 | 0x88300000 | 1048576 | 1048576 | 1048576 | 000C |
        5 | 0x08400000 | 4194304 | 4194304 | 4194304 | 000F |
        6 | 0x08800000 | 54525952 | 54509568 | 54509568 | 000F |
        8 | 0x8BC00000 | 0 | 0 | 0 | 000C |
        11 | 0x8BC00000 | 0 | 0 | 0 | 000C |

        Note the 54509568 (~52MB) in the MAXFREE column -- that's the important
        part; Aquaria needs a partition with at least 46MB free in a single block."

    I followed his advice and the data showed on the attached image (psplink aquaria.png) confirms Andrew Church thoughts

All in all, there is not enough free RAM available (only 25MB or so) to play 
Aquaria (requires 52 MB) on psp's with 6.39-pro10fix1, 6.39-9.7 me and 6.39-pro 
nightly.

Did you remember to disable all your plugins ?

Of course. I disabled all my game plugins inside
Recovery menu -> Advanced -> Game plugin Disabled.
I tested so many times "Unlock Memory in PSP Games" enabled and disabled.

I must admit I have the same issue on my PSP 3004.
Tested it with 6.20 PRO-B10.fix and with 6.20 PRO Nightly build.

Perhaps the method to unlock extra RAM in 2g+ psp models does not work very
well at all, or at least has some issues.

The memory unlocker is 100% working.

Maybe this plugin needs that the memory stays in the kmem partition and not in 
the usermem partition as the procfw does.

Ask the author if he only uses user memory or both kernel and user memory.

Here is the answer from Andrew Church himself about Aquaria's psp memory
usage:

Aquaria uses only user memory, but it requires a contiguous user memory
partition of at least 52MB in size (e.g., 0x8800000-0xBC00000).

How is this supposed to work then?
There is no PSP that I know of, which has 52mb of user memory.

Aquaria apparently works on a PSP slim (2000) with CFW 5.00 M33. There is also 
this info at wololo's site:

I guess this game uses the UMD cache memory from the PSP slim. Have you tried 
to disable the ISO cache? (it uses the cache memory region) or enabling "Force 
high memory layout"?

Yes. I tested today Aquaria in my PSP go (PSP-N1001) on CFW 6.60 PRO-C2 with 
all plugins disabled (GAME, XMB and POPS) together with ISO cache disabled and 
"Force high memory layout" enabled. Unfortunately, I have the same outcome: 
When I start the game, the system returns to XMB. However, Andrew Church and 
wololo say it works on CFW 5.00 M33. I cannot test it myself because I own only 
a PSP fat and a PSP go.
