Instead of (almost unlimited), I wonder if it would be worth putting (over 2TB). It still paints the picture in the users mind that there is a difference and reading a number might be a better reference. Just a thought

I agree, although you don't want to create the false impression that GPT doesn't support drives under 2TB!

@mystyq Good point about adjusting the GPT description! By the way, I’m curious—has there been a sudden 2TB limit imposed on the PFS filesystem? I remember it previously supported up to 2TB with APA partitioning, so just want to confirm if there’s any recent change to this constraint.

@1247847495 It seems it has always been this way, although with Berion's APA-Jail scripts it is possible to use a hybrid APA/GPT disk which provides a way to keep access to applications and make use of larger disks for storing images |
|
Are there any issues with the apa-jail script? It can easily lead to infinite reboots and has a low success rate. This hybrid mode is prone to various problems.

Regarding changing HDD to "HDD/SSD/SSHD", I don't think SSHD drives are really used much these days, the term might be confusing, and just makes the text unnecessarily long. I think it would be better to change to the more understandable "HDD/SSD", which arguably covers SSHD drives anyway. |
|
@1247847495 I would ask in the Discord channel, Berion would likely be more than happy to help you out with it if that were the route you were looking to go |
|
I would just say drive, not HDD/SSD/SHDD Also..some use sdcard ;-) Like iFlash2PS2, SD2IDE or potentially IDE resurrector. Also, example of config is recommened. Juts saying |

Pull request overview
This pull request updates the README.md documentation to improve consistency, accuracy, and clarity throughout the OPL (Open PS2 Loader) project documentation.
Key Changes:
- Expanded HDD terminology to include SSD/SSHD support throughout the document
- Standardized file size notation from lowercase "gb" to uppercase "GB" for consistency
- Corrected spelling and grammar (e.g., "Homebrews" to "Homebrew", "choosen" to "chosen")
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
| All partitions created by OPL will be 128Mb (it is not recommended to enlarge partitions as it will break LBAs, instead remove and recreate manually with uLaunchELF/wLaunchELF at a larger size if needed). | ||

| HDDs are also able to be formatted as exFAT to avoid the 2TB limitation. Please see below in the `HDD` section for more details on this configuration. | ||

There are two spaces after "limitation." when only one is needed. Remove the extra space before "Please".

I didn't know that. Are there other SD alternatives or even non-SD card ones who also pose as a HDD/SSD/SSHD? Do the 3 SD card alternatives you mentioned work on Neutrino, which are their micro SD card compatibility, which are their game compatibility in OPL and Neutrino and are micro SD cards as fast as HDDs/SSDs/SSHDs? Why do you say "potentially" IDE resurrector? |
|
So far the only incompatibility that I can find is sdcards and psbbn dep by cosmic scale dont work. Itll boot and hange. But say iflash2ps2 but instead of using iflash solo, ivlash sata v10 works. I ordered that as well iflash compact flash. .. |
I wasn't asking about app compatibility but SD card one (i.e., if the SD card alternatives you mentioned didn't work with some SD cards) and game one in OPL and Neutrino (i.e., if OPL and Neutrino weren't compatible with some games on the SD card alternatives you mentioned). Anyway, are SD cards incompatible with PSBBN, at least? Does iFlash-Sata v10 work with PSBBN unlike iFlash-Solo? What about iFlash-CF, iFlash2PS2, SD2IDE and IDE Resurrector? Why did you say IDE resurrector "potentially" uses SD cards? Also, is there a difference between using a 2.5"/3.5" SATA SSD on the PS2 via network adapter and using a M.2 2242 SATA SSD on the PS2 via iFlash-Sata v10? Is the latter more incompatible than the former with games on OPL and Neutrino and apps and are there M.2 2242 SATA SSDs that are incompatible with iFlash-Sata v10? |
Sorry no longer going down this discussion as its not related to the vmc group problem |
What VMC group problem? It has to do with the text on README.md. |
|
Ah your right, wrong thread. Either way when sd card is pretty self explanatory. Mmce is 2TB limit, internal ssd is same limit as exfat: nearly limitless, and mx4sio...I dont remember nor care about mx4sio |
What do MMCE, exFAT and MX4SIO have to do with what I asked? |
|
It would indeed be good if this PR were completed. I would also like to improve the NBD section by linking to the documentation specific to each plugin: https://bignaux.github.io/lwNBD/plugins/memory/lwnbd-memory-plugin.html https://bignaux.github.io/lwNBD/plugins/atad/ lwnbd-atad-plugin.html https://bignaux.github.io/lwNBD/plugins/mcman/lwnbd-mcman-plugin.html ... and explain the framework's intentions a little more clearly. I get the impression that people don't realize its potential. |
|
I think it would be best to remove nbd and make it its own app as it has nothing to do with loading isos. |
|
I think the framework can greatly help consolidate OPL, and if I had some help, we could do fun things like in-game TAS. Automated testing... OPL doesn't necessarily have to be limited to launching games; it could also launch applets and serve as an application server. The direction of a project is primarily determined by the people who contribute to it. |

^Because MMCE, MX4SIO, USB and Internal HDD can be formatted as exfat...but they are not equivalents. Anyway its quite simple, if you wire up IDE on slim PS2...use whatever device you want: sd card, msata, compact flash etc. Depending on the adapter, there are limitations to max storage size. Discussions about Neutrino have nothing to do with OPL..... SD Cards in every test I have done and have had other users do...we have not had PSBBN DEP working past the Playstation 2 logo but again this has nothing to do with OPL. |
But I didn't ask about exFAT. So, it is possible to use other drives than SD/CF cards and M.2 2242 SATA SSDs just by wiring up IDE on the PS2 Slim. Do they work on the PS2 Fat as well? Are there already other mods (that aren't DIY but that can be ordered) that use drives other than SD/CF cards and M.2 2242 SATA SSDs? Do the mods that use SD cards allow for mini/micro SD cards as well? |
|
Yes...mini/micro sd cards is fine Adapt however you want...IDE to whatever... some things will not work or don't exist that I know of, like IDE to U.2 |
What about IDE to M.2 NVME? |
|
^Try to find one ;-) |
Why, it doesn't exist? |
