So with this i could make nspire games even thought I don't have one?

Hi, critor+ExtendeD+all: The new ndless SDK works just fine.Thanks!
Just for fun i've compiled a known SDL demo with a suggestive name 'Fire' by David Ashley: http://www.libsdl.org/projects/fire/

Maybe some newcomers will enjoy it too.

Nice to hear this
Did you have to adapt some parts of the original sourcecode of 'Fire'?

No, not at all, only the resolution and commented-out a single code line (you may check the source). So is quite portable. Cheers.

Cant it create on like wabbitemu?

Basically, no: too complicated.

For Clickpad & Touchpad OS, freely downloadable OS upgrades (containing a boot2) are enough to create a .img suitable for nspire_emu.
However, for the CX and CM, you need a boot1. Even if only a subset of boot1 would be technically required for setting up several ports and loading the boot2 (I mean - for instance, handling serial port communication wouldn't be a required feature for an alternative, emulator-only boot1), the same legal challenges as for distributing official boot1 would get in the way of distributing alternative boot1.
