Questions - Changing flashing new ROM

[dude]

I have a Dream that I Rooted and is running CyanogenMod ROM 4.12.2 ROM. I used the Apps2SD, so I can't take the sdcard out. Here are some questions that I have.

First, I'm thinking about trying WG-Build Y BFS - Without Ram Hack R1. Before flashing do I need to uninstall apps2d?

Second, Do I need to wipe my phone before flashing a new/different ROM?

Third, does the "memory hack" simply refer to the flashed Death SPL (Haykuro).

Also, has anyone tried KiNgxKxKlair-Hero-Eclair-v0.6 or heard anything about this ROM?

Phone: DREAM PVT 32B
Rom: CyanogenMod ROM 4.12.2
Recovery: CM 1.4 (Cyanogen pimped out recovery image)
SPL: 10.95.3000 (Hard SPL)
Radio: 2.22.19.26i

Yes you have to do a wipe before installing the other rom, which also takes away the apps2sd. It is recommended so that there are no issues due to conflicts from cyanogen to the new rom. I have tried that other rom, it appears to run ok on the g1 but a little slow and right now the camera does not work and there some other small glitches. This is due to no proper 2.x drivers for g1 and mytouch. All drivers currently used are made from scratch or modified by the community. This is why cyanogen will not release a 2.x version yet. He does not want sloppy work out in his name. I am running cyanogen's current rom 15.1 with little trouble on his apps2sd. And sd out. Some apps wil go crazy though but in his mods if you don't want this option then don't have an ext partion and it should automtically be disabled when installed. The ram hack takes 10mb of your ram and dedicates it elsewhere making your phone much faster. I am using it and with about 150+ apps and major mods I fly where as without it my phone just drags to the point I don't want to use sometimes.

Hope this helps you out.
