PSIV Recomp 0.4.0-beta (new battle menus, field menu, Continue, twelve save slots)

PSIV Recomp 0.4.0-beta, the first beta: new battle menus in the style of a new field menu, shops to match, a launcher that takes you straight back into your game, twelve save slots, smoother battles and sound, and diagonal walking. A native port of Phantasy Star IV (Mega Drive / Genesis).

It ships none of the game. You need your own Phantasy Star IV (USA) ROM (.bin, .md, .gen, .smd or the .zip); the launcher asks for it the first time.

New since 0.2.0-alpha

• New battle menus (Enhanced): the field menu's framed windows in battle. Each party member has a window with their portrait, HP and TP, and what they'll do this round; the one choosing is outlined in gold and the others go faint. One bar under the party holds what you're choosing: Command, Macro or Run, then the five commands, then the technique, skill or item with a line on what it does, or who it's aimed at. Left and Right move along the bar.
• A new field menu (Enhanced; Settings > Game > Menu): the camp menu on the whole screen in framed windows. Items, Techniques, Skills, Equipment, Status and Macros are each laid out anew: the party always in view with HP and TP, full lists side by side, a line on what everything does, and on the equipment screen every stat with what it becomes before you commit. Shops show who can use each thing and what it would do for them. The menu is still the game's own underneath, so everything works as it always did.
• Mouse and touch in the menus: click or tap a row to pick it, right click to go back, the wheel moves the cursor.
• Windows: the audio hitches are gone. The sound device was being opened in a way that made Windows fall behind every few minutes; it isn't any more.
• Continue, from the launcher: one press takes you into the last save you made, past the logo and the title, in well under a second. Start game still goes to the title screen.
• Twelve save slots (Enhanced): four pages of three. In the game's Save window, Left and Right turn the page; in Continue and Erase, go past the last or the first slot. Each page is an ordinary save file, so they still load in an emulator.
• Smoother battles: the port's own picture is now drawn on several processor cores, and a machine that still can't keep up gets it a little less sharp instead of a slower game. A battle frame takes about half the time it did.
• No more stalls when a song first plays with your own music files: they load in the background now.
• Diagonal walking (Enhanced; Settings > Controls): hold two directions and the party walks diagonally, a tile at a time. No cutting corners; doors, exits and people are still met straight on.
• A new launcher: the logo on the left, the choices on the right, and Her Last Breath playing from your ROM (or your own file for that song, if you play your own music). At the top right, the notes switch the music off and on, and the Discord button (or D) opens the project's Discord server.
• The title screen in Enhanced mode says what this is: a IV beside the logo, and RECOMP under it.
• Linux: a stall of up to most of a second when a USB device came or went is gone.
• Fixes: in battle, a party member already down keeps their place; every Settings page shows all its rows.
• For reports of slowness or sound trouble: start the program with PSIV_PERF=1 set and send psiv.log.

What's in it

• Classic or Enhanced: the original game exactly as it was, or every addition, one switch on the launcher.
• True 16:9 widescreen drawn from the game's own maps, with optional side panels showing the party.
• Modern text and modern menus: full names, portraits, and what every technique and item does.
• Battles with depth: layers, drifting fog, light and sparks; the whole party in view; a battle camera; battle weather (storms, rain, snow, mist, space debris).
• Living water and swaying trees; the party's voices in battle; a Journal with the story so far and a hint when you're stuck; cheats.
• Sound: the original chips, or Algol, the port's modern sound chip; 32 new synthesized sound effects; play your own music files in place of any song; separate volume sliders.
• Rewind: fades to white and back about ten seconds (L1 / Backspace / the menu). Fast forward, rumble, gamepads, mouse (click to walk) and touch.
• Voice-over pack, a separate download (the lines are SEGA's, so it isn't part of this release): AI voices for 16 story scenes. Install it from Settings > Sound > Voice pack.

Known

• Beta: the newest parts (the battle and field menus) have had the least play, so please report anything odd. The battery saves are the game's own (saves/psiv.srm, and psiv-2.srm to psiv-4.srm for the further pages).
• In battle with five in the party on a 16:9 screen, the members' windows are narrow: small portraits, and HP and TP without their labels.
• The macro list still opens where the game puts it, over the leftmost member.
• The game's own windows still number the slots 1 to 3 on every page; the line at the top of the screen says which of the twelve they are.
• The field menu shows the game's short item names ("Titn-Sword"), and the Save and Start-button windows are still the game's own.
• Zio's battle background isn't widened yet: its edges show in widescreen.
• Reports and ideas: open an issue, come to the Discord, or MotaviaWorks@proton.me.

PSIV Recomp 0.2.0-alpha (living water, battle camera, voices, Journal)

PSIV Recomp 0.2.0-alpha: living water, swaying trees, a battle camera, the party's voices in battle, a Journal, cheats and volume sliders. A native port of Phantasy Star IV (Mega Drive / Genesis). The game's own 68000 code is recompiled to C and runs directly on your machine.

It ships none of the game. You need your own Phantasy Star IV (USA) ROM (.bin, .md, .gen, .smd or the .zip); the launcher asks for it the first time.

New in 0.2.0

• Living water: ripples, light, glints and foam on the sea, rivers and pools. Trees sway in the breeze, light flickering through their leaves. (Settings > Display)
• Battle camera: when an enemy attacks someone, the view turns to face them and the party slides along. (Settings > Battles > Camera; needs battle depth)
• Voices in battle: the party shouts as they attack, grunts when hit, breathes as they cast, cries out when they fall and cheers when they win. The voices are AI-made placeholders for now; files of your own in a voices folder replace them. (Settings > Sound > Voices)
• Journal, in the menu: where the story stands and what to do next, a hint if you're stuck, the story so far, and the Hunters' Guild jobs. A note in the corner says when the story moves on.
• Cheats, a new Settings page (all off unless you choose them): full HP or TP, no random battles, maximum meseta, double or quadruple experience, enemies at 1 HP.
• Volume sliders: separate levels for the music, the effects and the voices (Settings > Sound). At 100% the sound is exactly as before.
• Voice-over pack, a separate download (the lines are SEGA's, so it isn't part of this release): AI voices for 16 story scenes, from the opening narration to Zema. https://drive.google.com/file/d/1JMIdCscO566ShhHbF6mN4e_K-w3dKNdz/view (30 MB). Install it in the game: Settings > Sound > Voice pack, then pick the .zip (or put the .zip in the game's folder before starting). A music pack of PsiLok's remixes is coming.
