The '''Major Stryker save game format''' is used to store a saved game [[Major Stryker]], up to 10 in total. Each save will be named 'SR*.MS', with the asterisk replaced for letter A-J for save slot 0-9 respectively, though there is also a letter N used to hold the list of names corresponding to each save slot file.

== File format ==

=== Header ===

The file begins with a single byte checksum in order to prevent tampering. The checksum is generated by summing most of the bytes in the save game file into a byte value, and throwing away the overflow. The first byte (the checksum itself) and the last two bytes of the file are excluded from this sum. The same algorithm is used to calculate the checksum of the [[HS Format (Major Stryker)]].

'''Major Stryker''' is an EGA top down shooter, similar to the later VGA games [[Kiloblaster]] and [[Raptor]]. Its file formats are very similar (in some cases identical) to [[Cosmo's Cosmic Adventures]] and [[Duke Nukem II]], both of which were produced around the same time by the same developers.

Major Stryker Save Game Format

2019-04-12T16:42:24Z

Adambean: Created page.

{{Playerdata Infobox
| Config = Yes
| Storing = Saves
| Games =
{{Game|Major Stryker}}
}}

The '''Major Stryker save game format''' is used to store a saved game [[Major Stryker]], up to 10 in total. Each save will be named 'SR*.MS', with the asterisk replaced for letter A-J for save slot 0-9 respectively, though there is also a letter N used to hold the list of names corresponding to each save slot file.

== File format ==

=== Header ===

The file begins with a single byte checksum in order to prevent tampering. The checksum is generated by summing all of the bytes in the save game file into a byte value, and throwing away the overflow. The checksum is initially salted with an apparent varied amount. (To modify a save file make tweaks then add/deduct the delta of your changes to the checksum.)

{|class="wikitable"
! Data type !! Name !! Description
|-
| BYTE || checksum || Checksum of the file.
|}

=== Data ===

{|class="wikitable"
! Data type !! Name !! Description
|-
| INT || Fire power level || 0x01: Single shot forward 0x02: Double shot forward 0x03: Tripe shot forward 0x04: Triple shot forward cone 0x05: Triple shot forward cone + rear single 0x06: Triple shot forward cone + rear single + side single
|-
| NULL || Unused || N/A
|-
| INT || Lives || Count
|-
| NULL || Unused || N/A
|-
| INT || Shield level || 0x00: No shield 0x01: Side shields 0x02: Spinning shields 0x03: Bubble
|-
| INT || Burst level || Level is minus 1. (0x00-0x07 represents 1-8 respectively.)
|-
| NULL || Unused || N/A
|-
| INT || Zap bombs || Count
|-
| NULL || Unused || N/A
|-
| INT || Level || 0x00-0x23 for level 1-36 respectively. (0x00-0x0B for Lava planet, 0x0C-0x17 for Arctic planet, and 0x18-0x23 for Desert planet.)
|-
| INT || Skill || 01: Beginner 02: Novice 03: Expert

|-
| NULL || Unused || N/A
|-

|-
| NULL || Unused || N/A

| CHAR[...] || Score || Player's score, EOF terminated.
|}

The 6 unknown bytes above possibly consist of rapid fire time remaining and high speed time remaining. (As saves are always at the beginning of a level there isn't much left that would need to be stored.)

== Save slot names file format ==

=== Data ===

Each save slot is represented in the save slot names file by up to 24 bytes sequentially. There is no header or footer. Data is per-slot, with each following slot concatenated to its previous slot.

{|class="wikitable"
! Data type !! Name !! Description
|-
| CHAR || Slot number || Number is in ascii (0x30-0x39 representing slots 0-9 respectively), space (0x20) terminating.
|-
| CHAR[0-22] || Slot name || Save slot name up to 20 characters, CRLF (0x0D,0x0A) terminating.
|}
