Go to SM mode. Open the research screen. At the bottom of the technologies box (just below center) will be two new SM-only buttons: Instant and Instant RST. Select a tech you want, hit "instant", and you have it. To the far right of these buttons, below your list of scientists, is a box with your remaining points to spend. Each tech costs the same as the # of RP's needed to research it.
Instant RST will instant research all techs you have designed via missile, turret, or design button.
Be aware that since you are in SM mode, you can spend more points than you have available, so watch your total remaining.
