Well, I was toying around with the UPMS Installer, DCv4, and my PSP, and I found that you can make a sort of dual-boot with either one of the unbrickers. So why not share it with you guys?
So, here we go.

Why not use the UPMS Installer?

Well first off, this takes 150MB. That's with everything installed afterwards. For those using 128MB sticks, this wouldn't be sufficient. Even without the keys dumped (Phat=20MB), it still won't be enough.

So with that out of the way, let's begin. You can only have version of the unbricker installed so pick one. This guide will go both DCv3 and DCv4

Despertar Cemeterio Series

Pandora rules still apply. You will need a PRO DUO MS 128MB or higher. Less than 4 gigs. (4 gigs work) Also, you will need a Pandora Battery. (And that's just common sense when it comes to Pandora)

First, you will have to download this to reformat your MS. Yes, I said what you just read. Backup all data before doing this.

Download

When it download it, extract all contents to your desktop. Move 'msinst' to C Now, launch command prompt (Run > cmd)

Type this when it comes up:

mspformat.exe X

.

This will appear:

C:\mspformat>mspformat.exe X
You are about to format the drive X.
All data will be lost. Do you want to continue? [Y]

Press Y and hit enter. When it is done, disconnect USB Mode, and take out your MS. Shutdown the PSP. Reinsert MS, and reboot PSP. Head back to USB Mode.

Now, with DC there's only 1 thing you will have to decide. Which version to use.

Version 3 will install 3.71 M33-2, and Version 4 will install 3.80 M33-5. Whichever one you choose, download it.

DCv4
DCv3

Once you download your version, extract it. Move the 'despertar_cementerio' folder to X:/PSP/GAME. Now, download the following update eboots.

1.50 EBOOT
3.40 EBOOT
3.71 EBOOT for DCv3
3.80 EBOOT for DCv4

Once you download the right EBOOTs, extract and rename them to '150.PBP', '340.PBP', '371.PBP' and '380.PBP' respectively. Move them to the root of your MS.

Now, go make DC with the installer. (Launch from the XMB)

Once it is done, you will have to download Booster's Multi-IPL.

[Link is above. If you downloaded everything thus far, go back to the sendspace download]

Extract, and move the ipl folder to the root of your MS. Extract the 'Install-Multi' file to your desktop. Disconnect USB Mode from your PSP. Launch the cmd script, and then reactivate USB Mode on your PSP. You will get a whole lot of text on cmd. Press Y and hit enter to write the ipl.
When it is done, press any key to close 'cmd'.

Now here comes the fun part. Make Pandora Battery any way you want to. (Don't ask how to)

When you do that, insert the Pandora Battery, and Magic Stick into any PSP. Turn it on. It should boot straight to the XMB. Now, shutdown your PSP, and hold L, and reboot. The reboot should be quick and it should boot into Despertar Cementerio. From there, you should be able to do the stuff from DC. To shutdown the PSP, shutdown normally.

If you made it this far, you have a working dual-boot with Despertar Cementerio.

Note:You can still use your MS as a regular one. Just do not delete anything created by Despertar Cementerio off your root. (Kd, registry, vsh, data, etc. etc.) If you do, you will be running a bricker instead of an unbricker. Which is not good as DC doesn't have USB functions.
