just what I did when this hit me when I was younger:
1) get a job/part time job/whatever that gives you income in legit way
2) buy handheld. PSP, or even better, DS
(here I will make updadet version, as it was years ago)
3) get flash card
4) find Pokemon, late gen 4 and all gen 5
5) mod it with Drayano hacks for better difficulty curve and ability catch all 649 Pokemon and most before E4
6) Parents ***** that you play after midnight? Well sorry You earned money for this so they can gtfo. This is how it works kid
