[Q]ROM/RAM Upgrades?

---

Hi, I've seen a lot of cooked ROM in this Elf Upgrading Thread and I was wondering how are they changing the RAM(Program) size? isn't it RAM, supposed to be a CHIP and not a program or some sort?

Here's the screenshot, release notes, and links of some ROM with different Storage & Program sizes

They indicate how much ram is free with this rom, not how much ram you have in total.

@havoncnl I do fully understand what RAM or ROM does, but what I don't understand is, how are they changing the sizes of HTC's Total RAM?

Elfin has 256mb Total Storage and the picture you put in the first post indicate that the free space is 161.77 the rest is occupied by the operating system (ROM) Also it has a RAM 128mb and the free is 75.53 (The rest is needed for ROM to function)

This is what cooked roms all about, by adding and removing stuff from original roms they can vary its size and ram requirements and inturn vary the remaining free space

Ha funny seeing Nullstring was also an Elfer, not an Elfin
