From 33cb13dee5a527ac445ea1b13d42723e4eb3e3b0 Mon Sep 17 00:00:00 2001 From: Franklin Wei Date: Mon, 13 Oct 2014 21:00:47 -0400 Subject: Xworld - Another World interpreter for Rockbox Co-conspirators: Franklin Wei, Benjamin Brown -------------------------------------------------------------------- This work is based on: - Fabien Sanglard's "Fabother World" based on - Piotr Padkowski's newRaw interpreter which was based on - Gregory Montoir's reverse engineering of - Eric Chahi's assembly code -------------------------------------------------------------------- Progress: * The plugin runs pretty nicely (with sound!) on most color targets * Keymaps for color LCD targets are complete * The manual entry is finished * Grayscale/monochrome support is NOT PLANNED - the game looks horrible in grayscale! :p -------------------------------------------------------------------- Notes: * The original game strings were built-in to the executable, and were copyrighted and could not be used. * This port ships with an alternate set of strings by default, but can load the "official" strings from a file at runtime. -------------------------------------------------------------------- To be done (in descending order of importance): * vertical stride compatibility <30% done> * optimization <10% done> Change-Id: I3155b0d97c2ac470cb8a2040f40d4139ddcebfa5 Reviewed-on: http://gerrit.rockbox.org/1077 Reviewed-by: Michael Giacomelli --- apps/plugins/xworld/bank.h | 55 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 apps/plugins/xworld/bank.h (limited to 'apps/plugins/xworld/bank.h') diff --git a/apps/plugins/xworld/bank.h b/apps/plugins/xworld/bank.h new file mode 100644 index 0000000000..6f280c5271 --- /dev/null +++ b/apps/plugins/xworld/bank.h @@ -0,0 +1,55 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2014 Franklin Wei, Benjamin Brown + * Copyright (C) 2004 Gregory Montoir + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ***************************************************************************/ + +#ifndef __BANK_H__ +#define __BANK_H__ + +#include "intern.h" + +struct MemEntry; + +struct UnpackContext { + uint16_t size; + uint32_t crc; + uint32_t chk; + int32_t datasize; +}; + +struct Bank +{ + struct UnpackContext _unpCtx; + const char *_dataDir; + uint8_t *_iBuf, *_oBuf, *_startBuf; +}; + +/* needs allocated memory */ +void bank_create(struct Bank*, const char *dataDir); + +bool bank_read(struct Bank*, const struct MemEntry *me, uint8_t *buf); +void bank_decUnk1(struct Bank*, uint8_t numChunks, uint8_t addCount); +void bank_decUnk2(struct Bank*, uint8_t numChunks); +bool bank_unpack(struct Bank*); +uint16_t bank_getCode(struct Bank*, uint8_t numChunks); +bool bank_nextChunk(struct Bank*); +bool bank_rcr(struct Bank*, bool CF); + +#endif -- cgit v1.2.3
