Help! Having issues booting macOS Big Sur using OCLP!

So, for the past days, I've been trying to get OCLP into a Compaq 510 (an old notebook from 2009) to run macOS Big Sur, and I've stumbled with a lot of errors.

I have a 16GB pendrive and an HDD: I've downloaded InstallAssistant.pkg file from MrMacintosh to the external HDD, expanded it using pkgutil and put it into an .app file using the tar command and moving some things here and there, and it seems to be working, I've done all that work using my Macbook Air I have from 2017, because thats the only one I have with USB-A ports. The app turned out different this time, it was a single .app file weighing around 12GB, which is what I was aiming for, because in my previous attempt I didn't "extract" the payload, so I ended up with a bunch of folders and files, including the app, that was 40MB. I ran OCLP on the pendrive to create its files in the EFI partition and then later used BootInstall_X64.tool to enable Legacy Boot.

So in this attempt (my latest), it didnt work at first, so I started tinkering the config.plist file using ProperTree, to, for example, making it recognize the Compaq keyboard and external mouse (the mouse isn't working, though), and I got to an error that I couldn't pass: OCB: Loadimage Failed: Volume Corrupted, so I used some other posts and guides as references, such as these: https://www.reddit.com/r/hackintosh/comments/qvg0ck/ocb_loadimage_failed_unsupported/ , https://www.reddit.com/r/hackintosh/comments/18ql39k/opencore_wont_boot_the_installer_ocb_loadimage/ .

I managed to make it go past that screen, but I stumbled upon another error: [EB.BST.FBS|!] Err (0xE) <- EB.RH.LRH, and this one: [EB.RH.LRH|P!] Err (0xE) <- EB.LD.LF. So I again started browsing the internet for tips, and I found these posts: https://www.reddit.com/r/hackintosh/comments/1h6jb2u/stuck_at_ebrhlrhp_err0xe_ebbstfbs_err0xe/ , https://www.reddit.com/r/hackintosh/comments/11xrxy8/stuck_on_err0xe_ebldlf_err0xe_ebrhlrh/ and this guide: https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/kernel-issues.html which happened to mention my error ([EB] something), so I did a couple things that it asked, and I managed to get out of that error.

But I hit a wall, again. Now the computers boots, I select Install macOS Big Sur on the boot picker and it just black screens for eternity, no response AT ALL.

My specs for the Compaq 510 are:

Intel Core 2 Duo T5870 2GHz

4GB of RAM (possibly capped to 2GB by the processor)

256GB HDD

GMA X3100 I think.
