{{#seo: |title= (Computer) - GameBrew |title_mode=append |image=zxadvance2.png |image_alt=ZXAdvance }} ZXAdvance is ZX Spectrum emulator for the Gameboy Advance. It is written in 100% pure ARM ASM for maximum speed on real hardware. It was submitted to the GBAX 2003 Coding Competition (Runners Up). ==Installation== Requirements: * A Gameboy Advance, or emulator. * A Flash Cart & Linker. * A PC with a Windows operating system. * Z80/SNA Snapshots. * Pogoshell (optional). Note that ZXAdvance does not work with multiboot cables. Creating ZXAdvance binaries (ZXAdvance Standalone): * Run ZXA.EXE and add ROMs to the list. * Double click ROMs in the list to change the controls, or ROM name. * Click the Create button to generate a standalone binary. * Upload this to your GBA flash cart. Creating ZXAdvance binaries with [[PogoShell GBA|Pogoshell]] (ZXA4Pogo): * Run ZXA.EXE and do not add any ROMs to the list. * Click the Create button to generate a Pogoshell binary. * You can optionally tell ZXA where Pogoshell resides on your PC, and ZXA will then automatically create the binary in the Pogoshell filesystem, and compile Pogoshell for you. ==User guide== '''General:''' * Load ROM (not available in ZXA4Pogo) - With preview option. * Exit to Pogoshell (only available in ZXA4Pogo) - Returns to the Pogoshell menu. * Reset ROM - A quick way of reloading the currently selected ROM image. * Reset Emulator - Reset the entire emulator, and reload the initial ROM image. * Save/Load Snapshot - Allow you to save and restore upto two ROM states (GBA internal memory). * Save/Load SRAM - Allow you to save a single ROM state (SRAM on the flash cart). Note that ZXA uses the first SRAM slot. '''Video Modes:''' * Full Screen - Unscaled display. * Scale X - The screen is scaled to fit horizontally. * Scale Y - The screen is scaled to fit vertically. * Scale X & Y - The screen is scaled to fit horizontally, and vertically. * Platform Genre - The top two thirds are unscaled. The bottom third is scaled to fit (for games like Manic Miner). * Custom - You can set both the offset and the vertical and horizontal scaling manually. ** Changes are saved in SRAM and may be recalled at any time. ** Use up/down while pressing and holding A to change the settings. '''Video Effects:''' * Black & White - Uses a monochrome palette to render the video. * Fake Scanlines - Gives the impression of veiwing on a crap TV with scanlines visible. '''Brightness:''' * Normal - Optimal setting for GBASP/GBA with Afterburner. * Bright - For GBA's with exteral lighting solutions. * Dark - Not much use, except when using on emulators. '''Audio:''' * Use this option to simply enable to disable audio. * Optionally, just turn down the sound on your GBA. '''Emulation Settings:''' * Frameskip - Has four settings. Set to zero for no frameskipping. * R Register - How the R Register is emulated. It is optimally set to use the TStates, but you can override this to force it to increment the R register instead. * Renderer - Should fix some flickering games, but this is not currently working * Pause on Menu - Select this if you do not want the ROMs to continue emulating when you activate the menu. * Throttle - Choose this to disable the audio synching. This will allow some ROMs to run at an 'overclocked' speed (can cause audio glitches). * Show Intro - Select this to enable or disable the intro ROM. * Debugger - Not available in the public build. * Disassembler - Not available in the public build. '''Control Settings:''' * Redefine - Select this will present you with a list of GBA key states, and their bindings (A+Up/Down to configure). * Quick Redefine - Provides a quick way of configuring either Kempston or Cursor bindings. * Virtual Key - Select this to display a 'virtual' keyboard (press A to select key). '''Cheats:''' * Insert Poke - Not available in the public build. * Cheat Database - Not available in the public build. ==Controls== '''Menu:''' Up/Down - Highlight the required menu option A - Select an option B - Return to the previous menu '''Load ROM (not available in ZXA4Pogo):''' Up/Down - Select ROM Left/Right - View subsequent pages of ROMs (if >10) A - Preview ROM, Load ROM ==Screenshots== https://dlhb.gamebrew.org/gbahomebrews/zxadvance3.png ==Known issues== Although ZXAdvance is no longer in beta, this version does have some stability and emulation issues: * No cheat support/poke support (it's there but too buggy). * Renderer Interrupt sequencing does not work. * SRAM is not saved if you don't close the menus and reopen before exiting to Pogoshell. * Some ROMs (Head Over Heels for example), cause the subsequent ROMs to fail too. ==Changelog== '''Version 1.0.1a''' * The unskippable intro was removed. ==Credits== ZXAdvance uses the Amstrad ZX Spectrum ROM image. You do not need to provide this, it comes prepackaged with ZXAdvance. ZXAdvance uses a hacked version of Jetset Willy in its intro.
