I think I have come up with some foolproof controls.
PSP
anolog stick to move
Left trigger/right trigger- Look left/right
X-Activate
O-Cast spell
[]- Swing weapon if drawn
/_\- Jump
X + [] - Block
Down arrow- Draw/sheath weapon
Up, left, right arrows- Hotkeys
Start-Pause
Select-Menu
That's not really foolproof. Using the triggers for look controls is... it's just not very good. It's awkward. Even worse, you can't look up or down at all. There's also no stealth stuff in there.
I think that for the PSP, they could go in one of two directions. First one:
anolog nub to turn left and right and to move forwards and backwards.
Right trigger (hold) to lock on to enemies. If you aren't locked on, holding it makes you strafe instead of turn.
Left trigger to block.
Triangle jumps, Square attacks, Circle does magic, X activates, basically as you had it.
Down on D-pad to draw and sheath weapon, like you had.
Up on D-pad to activate/deactivate stealth.
Right to access inventory.
Left to access map.
Press Select to enter free look (use anolog stick for look controls instead of moving and turning), and again to exit it (probably exits automatically if you get hit).
Start button accesses character sheet and main menus.
Second one (better thanks to the placement of the nub, and probably the best way to do first-person games on the system, but it takes getting used to for people who aren't left-handed):
anolog nub for look controls.
Face buttons for movement controls (forward, backwards, strafing).
Right trigger uses whatever's currently equipped or casts prepared spells.
Left trigger blocks.
Down on the D-pad jumps.
Right on the D-pad sheaths/unsheaths currently equipped weapon.
Left on the D-pad either casts spells (if they aren't On Target effects) or prepares a spell that you can then cast by hitting the right trigger (if they are On Target effects).
Up on the D-pad to activate/deactivate stealth.
Start to access main menu.
Select to access character menus.
There's no hotkeys in either, but... well, when you have as little to work with as you do on the handhelds in terms of controls, you need to prioritize things, and hotkeys are
not a priority.
DS
Basically the same controls, but replaceing shapes with letters. However, the hotkeys would be on the touch screen.
However, there could be a second control scheme for DS.
Dpad to move. L to block. To cast magic, you would draw a shape on the touch screen that corrisponds with the spell (draw a flame for fire ball, or a cross for healing) For attacking you would draw a straight line in any direction, and your character would swing along with it. To block, you would draw a circle and hold the end of it. Sneaking could be a spell. Could be better than my other idea.
Oh no. No, no, no. I've played enough games on DS with gimmicky controls where you traced shapes for
everything to know that it's not a good idea. Use the touch screen for look controls, and maybe a couple of hotkeys,
maybe attacks (but not by slashing on the screen, more by tapping either an attack button or tapping quickly on enemies, but
not by tracing lines), but that's it. If you want to use stealth then you should be holding a button, not tracing arbitrary shapes across the touch screen.
Fitting the world onto the PSP could be very possible, I mean look at the GTA series, and Test Drive Unlimited, with the latter almost the same size as Oblivions, Cyrodiil World. And compared to its console counterparts, the only tone down in TDU is the exclusion of bikes. So a PSP Elder Scrolls, would of course have to be toned down, maybe removing a few boring quests, and pointless spells. But also that, adding a few more dungeons to explore and what not.
TDU and Oblivion aren't really the same thing. Ditto on GTA and Oblivion. There's differences not only in the visual quality of the worlds, but also in the depth and complexity - GTA doesn't really have
any dialogue, and the same applies to TDU from what I've seen. NPCs are, at best, fodder for your car's front fender. On top of that, it's basically just a big outdoor sprawl. There's lots of buildings, but they're all just sort of... there. You can't really go into the vast majority of them, or even do much of
anything with them. They're basically walls.
Basically, it's not just the size of the world that prevents the game from being on PSP. Really, that's not that major of a consideration - it could easily fit something like Morrowind given the amount of space on the UMD. It's actually running that world and everything in it that's the problem.
Failing that, go Homebrew, and make a fan game port. Just... dont sell it and it should be all right.
It doesn't work that way. Regardless of whether or not you're selling it, an unlicensed, unofficial port made without permission from the original creators of the game is illegal, and will almost inevitably lead to a cease and desist order (
especially if it was a port of either Morrowind of Oblivion, both of which are still being sold by Bethesda).
