According to a post on the Devsgen PSP forums, Sony has included an official ISO loader in PSP Firmware versions 3.50 and 3.51. The loader is called np9660.prx and will apparently let PSP users load ISO files off their memory sticks. Once again, this feature wasn’t mentioned in the official change log, but it could be because Sony is planning to allow ISO downloads in the future.

Sony could be planning to release downloadable PSP titles either through PSN or a similar service geared exclusively for the PSP. The company has already mentioned earlier this year that a download service for the PSP is in the works.
French PSP news site PSP-Generation also notes that Dark_AleX and Mathieulh will be patching the np9660.prx file for use in Custom Firmware 3.51 OE.

Dark_AleX will not be releasing Custom Firmware 3.50 OE, as previously reported. Instead, Dark_AleX is working on Custom Firmware 3.51 OE to save time and utilize Sony’s most current firmware version for the PSP handheld system.
There has been no time frame yet for when 3.51 OE will come out, but rest assured that we’ll be reporting it as soon as it does.

So far, the features of Custom Firmware 3.51 OE are still unknown but hopefully we will have more details closer to the release.

The Resistance: Fall of Man update was announced a few days ago and we finally have some more information as to what it contains. The update is to be released later on today and will include a number of additions, including two new multiplayer maps, Westmorland and Cambornethat, can be purchased from the PlayStation Store. See below for a list of what to expect.

• Access PS3 friend list from in-game
• In-game option to report abusive players
• Voice chat using TV Speakers (if you don’t have headphones)
• Clan leadership transfer
• Penalty time enforced on people who frequently quit ranked games
• Ranked games that become unbalanced prior to launch will automatically be canceled in the lobby

UPDATE (29th June 2007, 3:33 PM):

The Resistance patch is now available to download and there has been a significant number of changes. Check out the detailed list below:

• Resistance: Fall of Man Map Pack 1 now available for download! This map pack contains both Westmorland, England and Camborne, England. Both are additional multiplayer maps designed to be played with Resistance: Fall of Man. Westmorland features snowy hills and Chimeran architecture. Great for snipers! Camborne features both above ground and underground fighting introducing a new twist on team battles. Both maps support all Resistance multiplayer game types. You must own Resistance: Fall of Man to play either map. To make purchasing and downloading the map pack quick and easy, there is now a “Purchase” button on the main online menu. Going to the “Purchase” menu will allow you to select, purchase, and download the map pack from within Resistance
• Worldwide Servers! Now you can play with your friends anywhere in the world since all Resistance servers are now connected to allow for worldwide play. There is a new option in the “Multiplayer Options” menu called “Worldwide Player”. Setting this to “Worldwide” will allow you to play games against other players all over the world. Setting it to your local region (North America, Europe, etc) will restrict your games to only allow other players from your region to join, and will guarantee that any players you are matched against when playing ranked games are from the same region as you. If you create a party, your party will use the Worldwide Play setting from your multiplayer options (ie, if you are set to “North America”, only north American players will be allowed to join your party, but if you are set to “Worldwide”, anyone can join). Players who are set to “Worldwide” may still join games created by players who are set to their local region only as long as both players are from the same region.
• The XMB Friends list is now accessible from the R:FoM Lobby. To access it, go to “Community” and select “Friends”.
• The “Map Vote” option has changed. There are now three settings: “No”, “Free Maps Only”, and “All Maps (Map Pack Required)”. Setting “Map Vote” to “No” will allow anyone to join who has the map that the game is being played on, setting it to “Free Maps Only” (not available if you begin the game on a map from the Map Pack) will allow players to vote for any of the free maps and allow anyone to join the game, and “All Maps (Map Pack Required)” will allow players to vote for any maps, including map pack maps, but will require anyone attempting to join the game to have the map pack. “Map Vote” will default to “Free Maps Only” for any of the free maps and “All Maps (Map Pack Required)” for any of the map pack maps.
• There is a new filter on the “Find Games” screen for custom games: “Map Packs”. It has two settings, “Free Maps Only” and “All Maps”. “Free Maps Only” will show only games that do not require the map pack, and “All Maps” will show all games.
• The “MUTE” menu from the in-game start menu is now the “MUTE/REPORT” menu. Selecting a player from this menu will allow you to select either “Mute”, to mute all voice chat from that player, or “Report for abuse”, which will notify an in-game moderator that the player is being abusive by cheating, glitching, or otherwise violating the EULA. In-game moderators will then be alerted, and may observe the player to verify that he/she is being abusive. We reserve the right to kick players we have observed being abusive out of the game and/or ban them from playing Resistance: Fall of Man, as per our anti-abuse policy outlined in the forums on www.myresistance.net.
• Voice chat from other players will now play through your television speakers by default unless you have a headset plugged in. There is a new option in the “Multiplayer Options” menu from the lobby called “Mute Voice Chat”. Setting this to on will start all players muted when you join a game. Players may then be selectively unmuted from the “MUTE/REPORT” menu if you so choose. The “Mute Voice Chat” option only has an effect if you do not have a headset plugged in.
• Repeatedly failing to finish ranked games (either by quitting or disconnecting) will now incur a time penalty wherein you will not be allowed to join another ranked game immediately after failing to finish one. The time penalty begins at 0 minutes, and will build up to a maximum of 15 minutes if you fail to finish a high percentage (30%+) of your ranked games.
• Clan leaders now have the option to transfer clan leadership to another player from the clan menu
• Human player models will lip sync with incoming voice chat from that player
• If you have a USB keyboard attached to your PS3, holding down the buttons “1” through “0” will change your characters’ facial expression (human models only)
• Ranked games that become too unbalanced in the staging screen will be canceled by the server rather than launching with unbalanced teams
• In the lobby, L3 is now always the push-to-talk button so that remapping the push-to-talk button does not prevent you from being able to chat in the staging, party, or results screens.
• Player names drawn over friendly players will no longer be blocked by low cover to make it easier to distinguish friendlies from enemies.
• Players may now switch the virtual keyboard over to the full QWERTY style keyboard rather than the standard virtual keyboard if they so choose
• The staging screen in a deathmatch game now has a header to show you what race everyone will be when the game starts. Additionally, the loading screen will now also reflect what race you will spawn as.
• For Chimera vs Chimera team games, the skins used by each team have been changed to be more distinct
• For games with limited lives (such as conversion), the “QUIT” option on the in-game start menu will change to say “LEAVE” after you have been eliminated to indicate to you that you will not receive a Quit on your stats for leaving after being eliminated.
• Fixed an issue where you would hear splashing sounds on levels without water
• Fixed a problem that caused bullseye tags to sometimes remain active after the player they were attached to has died
• Fixed a number of potential collision exploits
• Fixed a problem that caused the rocket launcher reticule crosshairs to disappear when meleeing while a rocket is being held stationary.
• The per-team “Time Alive” column for team conversion now displays the correct stat rather than the total team score.

Gametype Changes

• Assault and Breach mode games have had the number of players required to create them lowered in Team Objective games, and the likelihood of these modes has also been increased.
• Chimera vs Chimera Team Deathmatch has been removed from the Team Deathmatch gametype.
• Conversion in the Free For All gametype has been changed so that players will have 5 human lives and 1 Chimeran life instead of 1 human life and 1 Chimeran life.
