The Parent-Clone XML DAT is a DAT for clearmamepro and RomCenter ROM managers. I addition to perform like other Parent-Clone DATs (like MAME one from Logiqx) it offers 2 new features which are based on user's ROM region preferences: - ROM merging - One game, one ROM (1G1R) list All Parent-Clone DATs follow contents (naming, hashes) in standard No-Intro DAT for a given system. Tested on: clrmamepro 3.119a and RomCenter 3.11 =================== ROM MERGING SUPPORT =================== Example: · · · WarioWare, Inc. - Minigame Mania (Europe) (En,Fr,De,Es,It) Made in Wario (Japan) Waliou Zhizao (China) WarioWare, Inc. - Mega Microgames! (USA) WarioWare, Inc. - Mega Microgames! (USA) (Beta) Watashi no Makesalon (Japan) Whac-A-Mole (USA) Whistle! - Dai-37-kai Tokyo-to Chuugakkou Sougou Taiiku Soccer Taikai (Japan) Who Wants to Be a Millionaire (Europe) Chi Vuol Essere Milionario (Italy) Qui Veut Gagner des Millions (France) Quiere Ser Millonario (Spain) Weekend Miljonairs (Netherlands) Wer wird Millionaer (Germany) Who Wants to Be a Millionaire (Australia) · · · The XML DAT can be used to merge a ROM collection. If user sets region preference to Spain > USA > Europe > Japan... listed ROMs in the example above will be merged into 5 archives named: WarioWare, Inc. - Mega Microgames! Watashi no Makesalon (Japan) Whac-A-Mole (USA) Whistle! - Dai-37-kai Tokyo-to Chuugakkou Sougou Taiiku Soccer Taikai (Japan) Quiere Ser Millonario Note the "family" archives (with more than 1 ROM) are named using untagged title from prefered region. Standard archives (single ROM) are named using title with tags as usual. ROMs inside the archives will remain named as listed in the example (no changes). To merge: In RC: 1. Load DAT. 2. Go to File->Preferences (Romsets tab) and set "Roms structure" to "Merged (All ROMs in the Main Set)". If you set "ROMs structure" to "Un-merged (All ROMs in both sets)", the P/C DAT works as the official No-Intro DAT. 3. "Fix" your ROMs. In CM: 1. Load DAT. 2. Go to "Settings" panel and configure your ROM paths as usual. Now using the dropdown box select "Regions", click "Select All" and finally sort regions using the "Move Up/Down" buttons. Top of list has the highest priority. 3. Go to "Scanner" tool. If you scan in "Unmerged Sets" mode, the P/C DAT works as the official No-Intro DAT. If you scan in "Merged Sets" mode, ROMs will be merged as described above, according to your "Regions" settings. However, it is recommended to merge using "Rebuilder" tool. NOTES: 1. While clrmamepro is able to create 7Z/RAR archives, it cannot create "solid" archives yet. If you want solid merged archives, use GoodMerge and the supplied XMDB file instead. 2. RomCenter merges ROMs as described below. However currently "family" archives (with more than 1 ROM) are named using untagged title from absolute parent ("DAT parent"), and not from user's prefered region. ========== 1G1R LISTS ========== 1G1R lists are list containing only 1 member of each family of games, the one matching the user's region preferences. If user sets region preference to Spain > USA > Europe > Japan... only 5 ROMs (vs 15) will appear on the 1G1R list WarioWare, Inc. - Mega Microgames! (USA) Watashi no Makesalon (Japan) Whac-A-Mole (USA) Whistle! - Dai-37-kai Tokyo-to Chuugakkou Sougou Taiiku Soccer Taikai (Japan) Quiere Ser Millonario (Spain) If you want to create an 1G1R list, you simply do the following: In RC: 1. Load DAT. 2. Select "Originals" database category to display the 1G1R list. You can select ROMs in the 1G1R list from your folders (to copy, move them, etc) by selecting a folder and using Edit->Select main sets. In CM: 1. Load DAT. 2. Go to "Settings" panel and configure your ROM paths as usual. Now using the dropdown box select "Regions", click "Select All" and sort regions using the "Move Up/Down" buttons. Top of list has the highest priority. Finally click the "1G1R Mode" radio button. 3. Go to "Scanner" tool. It will perform as if your were using a 1G1R DAT. You can use "Rebuilder" tool to create a 1G1R collection from your current one. NOTE: 1G1R list in RomCenter currently display "DAT parents", and not the parents corresponding to user's region preference settings.
