Little John NES module for PSP - Proof of Concept

Posted By: Tinnus

This is the PSP version of the NES module in the Little John emulator collection (formerly known as LJP or LJZ for PalmOS). It's currently undergoing a complete re-work and that includes a PSP port

Yes, eventually the full Little John suite will be available for the PSP too in its new and shiny version

But, for now, I bring to you only the NES module--not that it means little though.

Features:
- Full speed (@333Mhz and v-sync ON)
- Full screen
- Full sound at 44 KHz
- Full controls (D-Pad, X = A, O = B)
- Biggest mapper and overall compatibility ever (I'm yet to find a game that doesn't work)

Does NOT feature:
- Any type of configuration. Remember, this is a POC, not a full-fledged emulator with bells and whistles. The final version will have all the bells you want.

Instructions:
- Place the % and non % directories in /PSP/GAME if you're in 1.5 or /PSP/GAME150 if you're in 2.71SE or 3.0X OE.
- Place a NES rom file in the non % directory and call it myrom.nes.
- Launch it and play

Remember this is basically only to show off the potential of both the new LJ framework and the NES module itself... but it's still fun to play anyway

Technical addendum: The PSP port, with all it has, was done in less than a day (while doing other stuff). I suppose once I get the other modules working, they could be ported as easily as this one.

GPL addendum: I do know the NES module in LJP is GPL'ed but I have a reason not to put the source up for download... besides being lazy, the framework code is still being heavily worked on. Although if someone politely asks for it, I won't refuse. But I repeat myself--it's pointless for now since it's completely WIP at the moment. If you just want the code for the NES emulator, get the sourcecode from LJP at http://www.little-john.net . Thanks for your cooperation

Heart of The Alien for PSP - R1 is out

Posted By: Tinnus

Did you like the news about that oh-so-close Another World interpreter for the PSP?

Well, now you have the sequel! HOTA for the PSP is just released.

Remarks:
- Get an ISO image from the original HOTA game for the Sega CD.
- Don't ask anyone here (or me) where to get it, use your creativity (or google if you don't have any).
- The ISO file must be called "Heart Of The Alien (U).iso" and be in the same folder as the eboot.

Bugs:
- Some vertical lines in the display
- No music tracks
- Intro exits after one specific part

I'm working on solving both. The lines problem will go away soon for sure. About the intro I'm a little clueless, but you can just skip it for now using Triangle (see below). If you want so watch it just get the PC interpreter from http://hota.sourceforge.net

Features:
- Full sound effects
- Full screen display
- Quick Save/load -- that's a really good one! Never need to use those passwords again. Although you can still press Start anytime to go to the PW screen.

You need about 10KB for saving the game with Quick Save.

Controls:
- D-Pad: movement
- Square: run (hold and move) / shoot (see below)
- Cross: Jump
- Circle: whip
- Triangle: skip cutscenes, quit (although it's generally better to exit via the home button)

Shooting:
- Tap the button to shoot. Press and hold for a few moments to create a shield. The shield will disapeear after some time. Press and hold for even more time (the glow in the tip of the whip will get bigger) to release an energy blast, which destroys other shields, and some kinds of doors/enemies/machines.

Misc:
- In one part of the game you get two parts of a bomb and need to activate it somewhere. Press X, Square and Circle at the same time to activate the bomb.
